This is most definitely the case. It has also caused enormous problems for places where flooding was already a threat, by removing the natural buffering capabilities that places like wetlands have.
In fact, a whole field (stormwater engineering) exists to mitigate this.

It's In huge troubles as the old models do not hold up against new realities and all incentives are aligned against acknowledging that.

The again, neither insurance nor building pricing wants to reflect the new reality. A whole generation has invested "safe" in buildings and companies along "virtual flash flood funels" and embracing truth is like accepting your life's saving burning away.
One wonders when the first realistic model based tax write off ahead of time goes to court and pokes a hole into that reality. As in "I pay no taxes for what is most likely destroyed over the next ten years and will repay if it doesn't happen"..

This ethic of course only contributes to the problems of flash flooding, lack of buffer, lack of aquifer recharge, and (ultimately) alternating drought/flood cycles.
This drain, drain, faster faster is a question I've been keen to get to the bottom off as I live in an area covered by upcoming River Thames Scheme to help prevent flooding. As I'm doing a rewilding course I wanted to find out how much natural flood management techniques they were using as nature's solution is to generally hold water as long as possible in the landscape to slow down peak flow, as peak flow is generally what causes the worst flooding events. This also has knock on benefits helping mitigate pollution and soil erosion etc.
I've been to two consultations and am still none the wiser, though I've another consultation to go to.
Whether this is tree/vegetation cover or beavers (despite being in the middle of surburban sprawl, Ealing have secured funding for beavers as a potentially cheaper solution than hard infrastructure for flood mitigation and a significant amount of the beaver costs were the fencing to keep them in despite England having some wild beavers).
Similarly I've seen the Pennine Way in the South Pennines turn into a fast flowing stream during one period of wet weather due to the inability of the land to hold all the water and houses there get flooded as well.
Obviously the clash here is between the human and natural ways of doing things, building static houses on floodplains doesn't fit with more chaotic natural solutions in a dynamicly changing landscape with increasingly erratic weather patterns...

So the answer to this is HOA's....
Um, what? you say.
So here in the hill country of Texas housing developments/cities need to build so many feet of storage retention ponds per house built and impermeable roadway laid. Depending on the size of the development these are decently sizes structures and an off the cuff guess on costs is between 500k and a few million (+lost land to build more houses on) so it's a sizeable expense of developing. Cities themselves don't want to pay for and maintain these structures so they instead farm it off to a MUD/PUD.
https://services.austintexas.gov/edims/document.cfm?id=22701...
The MUD wraps up the expense of the roads, things like this water settlement area, and pools and puts the expenses on an HOA.

By now, I assume everywhere in the developed world requires retention ponds to be built to offset whatever land gets paved and/or is no longer permeable due to development.
Usually among the most costly line items of construction.

At least recently there are a lot of projects in various places to essentially build long pipe tunnels to hold water for treatment in storms and not overwhelm treatment plants.
DC is building one, London is building one, Paris is building one to make the Seine swimmable for the Olympics, etc.

I don't really know. I live in Washington, though, and we sure have a lot of man-made storage ponds.
Thanks. Hey it's a start!
Village Homes in Davis has an interesting distributed stormwater system, which was specifically designed to maximize infiltration.

I'm out duck hunting right now and there's quite a lot of very very damp farmland in the Seattle/Tacoma/Everett metroplex. The river valley behind microsoft would be idiotic to build anything bu farms and golf courses on (and the golf course is unplayable half the year). The term colloidal substance describes these areas well. Also a ton of water retention areas on the hills, otherwise stuff would wash out very easily.

I can think of some spots where four or five adjacent suburban developments will all have their own pond/catchment tucked away, although their appearance and attractiveness varies.

“A field exists to mitigate this” is a great way to end that comment.

"Traffication: How Cars Destroy Nature and What We Can Do About It" excellent book on ecological damage caused by traffication.
Some insights:
* traffic noise (soundscape pollution) is actually suspected to be the biggest ecological destructor affecting all levels of life from insects, to birds, to mammals.
* Traffic-related noise accounts for over 1 million healthy years of life lost annually to ill health, disability or early death in the western countries in the WHO European Region. (a)

That was one of the things I actually liked about Covid lockdowns: the absence of the constant, distant noise of cars and trucks.
How much of that swamp, marsh, and wetlands was drained in order to enable/improve farming and forestry? To me this has less to do with living patterns and more to do with commercial exploitation of land. I am unsure how much of a reduction in draining we would see if we remove cars and roads from the equation.
Looking at Sweden, there was a major movement in the last century to drain wetlands in order to improve timber production. This forestry policy is argued to currently produce about 1/4 of all green house gases released in this region, and a major cause to lower ecological diversity.

Much, much more. Industrial-scale agriculture is by far one of the most devastating things that humans do to the environment; my focus on roads wasn't meant to imply otherwise.
(The larger observation is that, while we use more land for agriculture than we need, there is at least a prima facie argument that industrial agriculture feeds our planet. Whereas a 6 lane highway through a drained wetland to a low-density suburb does very little for our planet.)

Not all agriculture even feeds the planet. E.g. cotton grown in the central valley of california makes its way to mexico to become budget metal spring mattresses. Does the world need more metal/wood/cotton boxes that end up on the side of the road at some point in their lifetime? State economic planners seem to think so at least.
A lot of farming would not be viable without roads. It's something of a blind men and the elephant question. Roads weren't originally developed for cars; the US Constitution prescribed the authority to build roads for the postal service. Roads, especially paved roads, make it possible to send fresh produce to markets in cities hundreds of miles away, to collect grains at mills, and to distribute and maintain farm equipment.
In warm regions, wetlands were also drained to control malaria, particularly in Brazil and the American South.

Whether it is car, bus, train, Uber or hovercar, we will still need roads. Until personal jetpacks and flying school busses are a thing, the road issue is totally divorced from the type and environmental impact of vehicles driving upon the. Some form of road will be there regardless of the means, or even the amount of traffic, so long as a connection is needed.
Of course we need roads. We just don't need all of the roads we currently have; many could be (and were, until very recently) eminently more sustainable forms of mass transit. Similarly, many of our roads could be narrowed and augmented to induce demand away from unsustainable development patterns.
The thing is that we choose the amount and type of traffic and therefore the physical size and area of our roads by planning choices that induce behavior.
“We will still need roads” is true, but the amount and size of those roads are important details. Not all roads are created equal - just ask your local bike path how many animals were killed in collisions.

Of course roads are needed.
But there are at least two problems with such a deceptively simple statement:
1) Road construction is constantly expanding. They create their own demand by diverting resources away from many things including affordable housing -- the number of people I know that commute for over an hour because they cannot afford to live near their work is non-negligible. At some point this becomes a planning/resource issue and at the moment the decision is to carry on as usual with a system that is causing major problems.
2) The amount of traffic makes a huge difference. It is well documented that roads create ecological bubbles affecting animal populations negatively. The speed and frequencey of the traffic (type of vehicle) makes a difference.

DDT in very particular situations has also been a net positive. It's really the widespread indiscriminate use of it in nature areas and dumping it by the ton into municipal sewers that caused the terrible ecological outcomes. Similarly, organising ourselves into sprawling suburbs (rather than higher density cities with sparse rural communities and nature areas in between) was ecologically, the less optimal deployment of roads.
I don’t think trains need as many roads as the other options in your list.
> much like we remember our grandparents for leaded gasoline and DDT
What? I associate DDT and leaded gasoline with my grandparents not-at-all. Is anyone here really holding their grandparents feet to the fire over these?
What? I associate DDT and leaded gasoline with my grandparents not-at-all. Is anyone here really holding their grandparents feet to the fire over these?
I don’t literally associate my grandparents with leaded gasoline. It was meant to be metonymic.
I don’t think dissolving the blame is particularly helpful here. A minuscule number of individuals had full control over the use and knowledge of the impact of leaded gasoline, and everyone else had absolutely none. For 99.999% of folks those people have no relation to their grandparents, and “blaming” an entire generation for the malice of a few is ill guided at best.
Blame is your phrasing, not mine. I agree with your point about knowledge and agency; I think future generations will look back on us with disbelief and shock at our shortsightedness, not blame.
Then when they're 50 they'll look back on stuff they thought was fine when they were young, and is bad now. If they're introspective they'll look at the stuff that their parents or grand parents or further back thought was fine and turned out to be bad. As people say, it's easy with hindsight and it's really hard in the moment. Many second and third order effects aren't obvious or testable. Then add profit motive. The real question is do you change when you realize you were wrong or double down.
It wasn't their fault, but the effects of lead on crime, personality, and mental health for that generation is clearly documented.
So yes, that generation is remembered for it. I don't think anyone is saying their grandparents deserved it or are to blame.

I think it's supposed to be read as "the generation that contains readers' grandparents" without literally being the specific ancestors in a personal context.
USA has plentiful water resources.
Engineering practices in new development and redevelopment have adapted to prioritize retention of stormwater. We have some of the finest and most sophisticated hydraulic engineering in the history of the world, be happy for what you've got.

All three of "we have plentiful water resources," "we have advanced ground- and storm-water management systems," and "we are disastrously compromising our water resources" can be simultaneously true.
I'm exceedingly thankful for my high quality of life. I would like my grandchildren to share a similar quality of life.

Since you're a fellow New Yorker, I'm also puzzled how you conclude there is a water scarcity problem? My first reaction was that you might be living in a water-stressed area. I'm sorry if my first comment sounds trite, it wasn't my intention. (Maybe I have social media fatigue?)
There's a trade-off between preserving the environment and having human development. We already remember our grandparents for the contributions they made to human development. Our lives are vastly better now because of it. Future generations will also benefit from our contributions, including the things we did using roads. They might have less aquifer water or whatever, but that's not really essential. We can always get water from other places if we pay more, and we can afford to pay more because of all the technology we're gaining.

I think most of the Great Plains disagrees[1].
I'm pro-technology and pro-development. But I don't think we should kid ourselves about what we have, and about the limits of our ability to geo-engineer ourselves into global homeostasis, versus out of it.

I don’t think vast suburban single family home housing developments, big box store parking lots and Wendys drive thrus are the drivers of technological development you’re making them out to be.
The overwhelming majority of environmental degradation is not being caused by cutting edge technological development. Wasteful and destructive development patterns are not what’s driving technological growth.

I'd say they're interconnected. Quality of life may help people be more productive or attract more productive people. Plenty of technology goes into consumer goods and services, and is sort of what the whole point of technological development is - making people's lives better. Also, the car industry was/is full of cutting edge technology and was enhanced by car-friendly housing and roads. It was a major factor in America industrializing in the first place.

It's simply not possible for many families to live in the cramped environments of a city. How am I going to pick up 12 gallons of milk on my weekly grocery shopping trip without a pickup truck? That's about 125lb of milk. Not going to be able to get that onto a fixie in the city. How am I going to park the truck without a garage? The garage needs 3 spaces, one for the truck, one for the car, and one for my garage refrigerator to hold the 12 gallons of milk. You're not going to find a house with a 3 car garage that hasn't been built on marshland.
Sites like this one like to browbeat hardworking Americans, but the reality is that not everyone can live an eco-friendly lifestyle. I'm not sure what the solution is but shaming people isn't it.

I'm not gonna argue with your choices in life, and I might make the same ones if I had a family that goes through 12 gallons of milk a week, but it's not impossible to pull that off with fewer cars and a smaller garage.
Scenario 1: dense urban living, somehow you can afford an apartment big enough for everyone. No car, just good transit (e.g. Hong Kong, Singapore, Tokyo). Grocery store is <3 minutes walk from the front door of your apartment, so you get 2 gallons every day. With a family that big, you're probably picking several items up, but you'd use a trolley (like this: https://www.argos.co.uk/product/8653909?clickPR=plp:4:6 or bigger: https://www.kmart.co.nz/product/foldable-beach-trolley-42365...)
Scenario 2: big terraced/row/town-house (shared walls on two sides), has a 1-2 car garage. Suburban-ish living, car dependent, but definitely not rural or outskirts of a city. You own a van, which you'd need anyway if your family is big enough to need 12 gallons of milk a week, and then you have your big chest freezer in the garage and you go once a week to the grocery store and get 12 gallons of milk.

The reality is that the rest of the developed world manages just fine living in houses without such garages, driving smaller cars. And having a family isn't a uniquely American concept. Of course everyone can live an eco-friendly lifestyle; for all but a tiny speck of human existence, everyone did indeed do so, and the majority of people on the earth actually still do so to a reasonable extent. It's not a "not everyone can" or "not possible", it's a "not everyone wants to".
There's no shame in my statement.
The US isn't the only country in the world with big families; there's seemingly nothing exceptional about us (in that regard) that requires the pickup truck and 3-space garage where other countries get along fine. Part of the reason they get along fine is because they allow grocery stores to be built on residential corners, so that you buy 3 gallons of milk every other night on your way home rather than driving X miles to load up weekly.

The problem is you're just overlaying suburban lifestyle on a city without adjusting it to suit your environment. The equivalent would be a city dweller moving to the suburbs and thinking they can just walk to Walmart, when it might be 10 miles away.
If you live in a city you can just pick up milk at a convenience store as you walk by, when you need it. There will probably be one within a 5 minute walk of your house.
I would also like to know more about this milk consumption. Median consumed by US milk drinkers is 1/3rd gallon per week - your family is drinking as much milk as 36 people do every week.

I think this may be a joke? https://www.independent.co.uk/life-style/12-gallons-milk-mem...
But anyway, we go through a lot of milk (significantly less than 12 gallons) and have it delivered. Same thing applies to anything large that I'd rather not rent a truck for.

yes
usually, when people are promoting alternatives to the car, these things need not be in exclusion to the car. In general, when a road is over a hundred feet wide, it is really not a big deal to provide an additional twelve feet for an ADA sidewalk, and maybe another twelve for a bike lane with more protection than a strip of fading paint.
the American car dependent lifestyle has mostly happened by making other lifestyles impossible. In other places you don't buy your milk for the whole week in one go, there are convenient supermarkets where you can walk in and out on your way to and from work on foot or public transport, so stopping in more frequently is a lot easier if you're not driving 15-20 minutes on arterial roads to the big box store. In most of America, it is illegal to open even slightly smaller grocery stores in areas outside big box arterial roads.

I'm glad to see someone standing up for hardworking folks like me on this elitist site. My family has found that converting one of these allows us to do the weekly shop of not just the milk, but also the charcoal for the barbeque and the tomahawk steaks for the children at the weekend: https://www.autotrader.ca/heavy-trucks/sanitation%20truck/
I have a couple of stories
1. Last Easter my wife and I were travelling across the country. We drive reasonably slow, mostly about 100km/h. I guess it was a special time of the year because we must've killed at least several thousand insects in the first two hours alone. It was non stop. One car out of thousands on the road. Made us feel pretty bad.
2. Second story is about four years old. Travelling on a brand new highway around Easter. I guess wildlife was not used to the road because the asphalt was - i kid you not - littered with squashed snakes and birds. I couldn't believe what I was seeing - several kilometres of straight road covered with untold amount of bodies. One of ugliest things I have seen.
Roads are absolutely horrible and I very much hate travelling because of stuff like this. I think some countries don't have such problems problems because they barely have any wildlife left.
It's a tragedy and barely anyone I know cares enough to even consider what we are doing.

For an awful observation on 1.: you might not have to worry about that soon. There's a common observation world wide that this phenomenon is declining, due to the horrific decline in insect populations.
https://en.m.wikipedia.org/wiki/Windshield_phenomenon
https://en.m.wikipedia.org/wiki/Windshield_phenomenon
The killing of insects thing is wild, one car seems to be able to create untold amounts of carnage to insect populations which would have some other function within the environment.
Where I live, there are frogs everywhere at certain times of the year after rain, people literally drive over hundreds of baby frogs per hour. I avoid driving after rain now.
But yeah, nice to hear from someone who has similar feelings about driving. I hate it for the damage it does. Tyre dust is another one.
I was recently doing a renovation and would only drive to the store unless absolutely necessary. I'd batch my shopping jobs. For me it's about emissions, I have a real problem with burning fossil fuels.

Road ecology is a very interesting and important field, particularly the modeling of animal interactions with road crossings - all very interesting and important.
The rhetorical title is absurd, however, and I'd argue even Ben Goldfarb would agree with that.
Habitat loss is the single largest driver of biodiversity loss, as a result of many, many drivers. You've heard of all of them. The presence and proliferation of roads is, of course, one of those drivers.

"We're in the middle of this biodiversity crisis and extinction event that is human caused, with cars kind of at the center of it in a lot of ways"
I'm just not that compelled by that argument. If cars are at the center, then so are a hundred other things that are impacting biodiversity at least as much.
I'm really not trying to be a car stan here, I don't really care about cars. But focusing on cars is kindof a dumb distraction, in my opinion.

It's not so much cars themselves as it is car-centric development that causes many problems.
In the US at least, this is pretty clear: when you design new areas and cities around cars as the primary or even only way to get around, this hurts the environment a lot more than denser, multi-modal style of developments. It results in more total space needed per person, and it results in higher energy expenditures.
If you look at vehicle miles traveled per capita, the US is around 2x that of major Western European countries, and nearly 4x that of Japan: https://publicinterestnetwork.org/wp-content/uploads/2022/02...

I wouldn't call it car centric, more like everyone-gets-to-have-a-lawn-and-2000-sq-ft-home centric.
Herein lies the crux of the problem, not in the mode of transportation. Americans are used to such huge spaces per inhabitant that driving appears to be the only option.
We have districts with detached houses where I live and to me they were always sort of a dead zone. No shops, no restaurants, not even a way to get across, as every square metre is someone's property, so at times you'll have to take a huge detour on the way to your destination.
Do the people living there drive everywhere? Apparently not all of them and instead they accept that they have to walk a significant distance to get to the next bus stop. All because they're used to having a lot of space and will never sacrifice it for an apartment in a place where everything is closer.
I wouldn't call it car centric, more like everyone-gets-to-have-a-lawn-and-2000-sq-ft-home centric.

Apartments are horrible. If you get a crying baby neighbor, or a dog, or neighbors who blast music at 3am, there’s nothing you can do about it.
Nothing. The police will not help you, as noise ordinance is not enforced. Your apartment manager won’t do anything because none of them do anything.
Other fun apartment specific happenings: constant clouds of marijuana smoke, curry spice smell seeping through the walls and sticking to everything, and constant thuds from anyone walking above you.
Without rigorous enforcement of rules, apartments suck. And there is no enforcement.

Suburban homes suck. If you get a neighbor mowing their lawn, weed-whacking, leaf-blowing, ignoring their dog endlessly barking outside, or partying late on their patio, there’s nothing you can do about it.
Nothing. The police will not help you, as noise ordinance either doesn’t exist or is not enforced. Your HOA, if you have one, won’t do anything because none of them do anything.
(Yes, this is tongue-in-cheek, but it is also rooted in real experience. Yes, I’m aware electric lawn equipment exists and somewhat improves some of the above when used. Nevertheless, city apartment living for me has been quieter than suburbia.)

Gas mowers are fast and run during the day. I couldn’t care less about daytime noise, because I sleep at night.
Animal control will eventually come for dogs left outside, but it takes some effort. The more property you own, the less this matters. And some HOAs DO enforce where apartments will not. HOAs aren’t in the business of making anyone happy, unlike apartments. They exist to do the opposite, in fact.

There are levels to apartments - I have lived in apartments like this in my 20s, but there is a whole world of single family condos that is more like my suburban childhood home. I live in a townhome in a dense area and experience no noise from neighbors beyond the occasional lawnmower or loud car. I’ve been able to find homes like that easily in urban centers in various parts of the US where I’ve lived.
> If you look at vehicle miles traveled per capita, the US is around 2x that of major Western European countries, and nearly 4x that of Japan:
You do know that the population density of the US is a fraction of that of the countries that you're comparing it to, right?
You do know that the population density of the US is a fraction of that of the countries that you're comparing it to, right?
Yes, and I also know this means that the US can spread out within metro areas, not that it must spread out. Did you know that?
I think you're right that cars are not a unique ill here. But I think it's worth observing that car-dependent societies disproportionately exhibit complexes of destructive patterns: car dependency goes hand-in-hand with insufficient urban design, poor transit networks, food deserts, etc. The latter aren't uniquely produced by car dependency, but are substantially aggravated by it.
I thought crime rates caused food deserts, not cars.
Edit: https://www.healthline.com/nutrition/food-deserts#locations-...
Concentration of the poor, and segregation are identified as the primary causes there. Not cars.

They're related phenomena. In general, sprawl (associated with car dependence) tracks with food deserts[1]. Reduce the sprawl, and you reduce the need for cars to access affordable, healthy food (and corresponding absence of access when people can't afford cars).

There are 2 billion parking spots in the US, enough to pave over the state of Connecticut.
Perhaps, but...
1. Roads being inextricably linked with car-dependence and urban development is clearly part of the implication
2. It is a pun!
It seems a bit needlessly nitpick to call it absurd, in my book.

My understanding jibes with yours: habitat loss in all its forms.
One thing you can do, in addition to advocating for public transit - if you have a lawn of short grass, grow native plants and let them get tall. They provide the habitats for animals that have gradually been taken away. Cut and burn the brush 1x/year and put some landscaping rocks between your house and the grass to encourage animals to stay in the landscaped areas, and you’ll be great.
Another benefit of this is - short grass holds almost no water because of the shallow root system, which means that during storms the water flows to low areas like your basement. Native plant gardens grow deep roots and absorb groundwater which would naturally move towards your foundation.
"Noise is really a form of habitat loss."
This really resonates. It's kind of obvious once it's stated, but the aural environment is part of the habitat. I bet the examples they give, such as owls listening for the sound of mice, are only a tiny subset of the ecological disruption caused by the noise of civilization, which is primarily road noise. Hopefully there will be more studies in the future like the phantom road noise experiment they mention.

I recall being taught that cowbirds, a brood parasite (they lay their eggs in other bird's nests), were causing more problems for other birds because they stay out of the deep forests, but roads and farm fields were fragmenting the forests.
They've certainly decimated the Tortoise population in the hi-desert near JTNP where I own property. Automobiles are way too fast for those to stand a chance.

You hit the nail on the head workout realizing it. The real problem is mass property ownership in remote areas. The huge uptick in car travelers and according roads are a result of that.

Yes | No.
The classic "road trueism" is If you build them, they will fill.
Four lane highways with occassional gridlock when expanded become six lane highways with occassional gridlock.
The connection corollary that follows is roads | train lines built to connect A and B will often be followed by small townsites along the way and the spread of "off the grid" living at blocks T junctioning dirt road access from the new A <--> B route.

Also, the roads built are for the most part free, which certainly doesn't help regulate usage at all.
The moment you introduce tolls onto major roads, often they don't meet financial projections, have to be bailed out, etc.

That's only when new roads satisfy pre-existing demand.
The fact that someone can't do something doesn't imply that they don't want to do it.

There are plenty of rural roads and highways that disprove your point.
We fill roads in cities because the population wants/needs to travel. If we would instead build trains those would fill instead. Trains are a lot more cost effective in cities, but no city (not even transit cities like Paris) builds enough of them to make trains a better alternative than cars.
Note that by the time anyone realizes roads are full and they need "one more lane" the road has 6 times more cars on it than it can safely handle - people just give up their safe following distance. One more reason to build trains.

It's not my point, it's a long standing observed principal of urban planning referred to as induced demand or induced traffic.
https://en.wikipedia.org/wiki/Induced_demand
https://www.wired.com/2014/06/wuwt-traffic-induced-demand/
My point was that road access introduced through previously road vehicle inaccessable regions often (not always) leads to more human activity and dwelling in the vicinity of that road.
It's not always the case that people appearing from ships, airdrops, or walking in results in roads following them.
When my own family first settled in Australia it took 80+ years on the European side for roads to reach them (they used flat bottomed boats on tidal flats to transit goods and livestock), and some 70K years or so on the non European side.

But nobody builds a road to nowhere. You only build a road when there is demand, often from property owners, to be able to reach a place more easily. Thus I repeat the issue is not the roads, they are merely a consequence of the property ownership increasing travel to a remote area.
Consider: would a road nobody traveled on be any issue for the tortoises? Clearly not.

Roads are built through "nowhere" all the time .. to join one city to another several thousand miles away with no other "civilisation" between.
To join a port to an inland mine site.
Once you have a road where once there was no road and no easy access to the land within then people can follow.
> But nobody builds a road to nowhere.
See: Gunbarrel Highway - a road system from a launch point out into "nowhere" in order to retrieve test missiles.

Connecting two occupied points is the exact opposite of building a road to nowhere.
And see my point here about “linear” roads (connecting point to point) vs space-filling ones (providing access to an entire grid of houses). In short, an animal can exist very easily in the proximity of a single highway, but existing surrounded by development is a much harder task.

Induced demand is a worthless concept. What they call induced demand exsits, but the name is misleading - better to call that latent demand. People want to do things and the city form isn't allowing them to. Once the city form allows it they will.
That it doesn't exist in rural areas improves that it isn't induced it is already there.

JTNP draws massive numbers of tourists. Plus the main road through my neck of the Mojave (62 and Amboy Rd.) is a popular alternate route linking LA and Las Vegas. You wouldn't believe how much traffic blasts through on weekends and holidays, most without even stopping. It's a lot of city folks driving like they're passing through an uninhabitable wasteland where speed limits don't exist.
The actual number of owners/residents like me out by my hood is on the order of hundreds, and most drive exceptionally slow in the hood because those roads are unpaved washboard insanity.
Airbnb/VHRs becoming a thing there and catering to the national park has made things much worse in terms of local vehicle traffic even on the dirt roads... but the Tortoises were already gone long before Airbnb even existed.
TL;DR: Tourism by automobile is the main problem, exacerbated by the draw of a popular national park. But even without it there's too much thanks to LA<->Vegas traffic.

“We aren’t the problem, it’s the out of towners that are the issue!”
Wouldn’t we all like to believe so much.
But in reality the roads taking folks all over JT and to/from Vegas cut the land into ~6 massive lattice cells. Those roads have basically 0 impact on turtle populations because their linear nature makes them effectively insignificant at the scale of the desert. On the other hand, the land ownership grid gives rise to a space-filling-curve of road that dominates the affected landscape and an effectively infinite number of microscopic lattice cells that are too small to support any population, and thus force the animals to migrate over roads constantly.

Government roads effectively subsidies access to land.

The parcels in question (near JTNP) are almost entirely empty BLM land that was bought up in masse by housing developers, developed, then cut up and sold to individuals. BLM wasn’t going around building gross grids into their parcels in hope to drive the value up for homeowners.
There's an argument which comes up often when talking about a society without a central government: "Who will build the roads?"
Besides the simple idea of neighbours building and maintaining small roads, I argue that I wouldn't want the highway.
Between the ecological damage, the noise, air pollution, increased reliance on shipping things from far away vs buying local - are we really sure building the massive road network in the US was the best option? Consumerism may be good for the economy, but I argue it's not in our best interest.
Sure, I love the freedom to drive fast anywhere but at what cost?
And who knows, maybe if we didn't have a central entity redistributing resources in an arbitrary way and shaping the market, some entrepreneur would have worked on flying cars and skipped the road altogether.

In practice, a society without a government is just a collection of local warlords depleting all the resources in a violent struggle for power.
For example, consider the history of Somalia or the general concept of a power vacuum.
So I'd think the chances of such an environment supporting an entrepreneur working on flying cars to be near zero.

I'm not sure why you've been downvoted at the time of my commenting; but you've probably upset someone who deserves to be upset. The sheer amount of space that is killed off in many cities to support roads and car parking is insane. If there wasn't that much dead space, walking around would be more than feasible.
Car-centric design sits in competition with pedestrian-centric design, and the bias towards road over-construction has ruined a lot of urban spaces. At the very least, rolling back government involvement in road construction would be helpful.

You can't have a walkable city, or any kind of city really, without a central government of some kind.
About flying cars, I don't think they are a solution to almost anything.
First of all, they'd always need more energy because staying in the air doesn't come free. Lifting a whole car for the usual 1.2 people in it seems wasteful.
Secondly, the noise problem would be huge. I don't see how flying cars could ever be more quiet than road-using cars (again, more power needed to overcome the drag that's generated by the lift, and propellers, jet engines or whatever aren't exactly quiet on their own). They'd also produce their noise up in the air where it can spread over a much larger area compared to land-based transportation, where even a small line of greenery reduces noise levels quite nicely.
Finally, even perfectly self flying cars (and obviously, I wouldn't want to have the average car driver handle a 3 ton flying machine over my head) would need a big amount of space around them in all directions. I doubt that there's enough air space to handle the amount of car traffic that even smaller cities currently have.
There's a reason we only see helicopters used in a small niche, and I don't think flying cars or the currently worked on drones are ultimately that different from helicopters.

How strange. I imagine the argument is propagated by the historically illiterate. When I think of the origins of modern roads, I naturally think of English turnpikes at the dawn of the industrial age -- all privately owned toll roads.

And the desire for recreation. The explosion of cars isn't necessarily that cars are so useful. Certainly they did have utility. But really they were kind of liberating. In the late 19th century, nobody ever heard of a vacation
We can see examples of other places where railways were the "liberating" technology that allowed people to go on holiday. For example:
Up to about forty or fifty years ago travelling was a solemn act, not to be enterprised nor taken in hand unadvisedly, lightly, or wantonly,’ so writes the Belfast News-Letter in September 1888. But all of this had changed; from the inception of the railways ‘day excursions’ had become ‘entirely modern pleasures,’ the British seaside and countryside opened up to visitors who could travel there easily by train.

Unknown. But if it means higher costs for routine shit. GFY. However, you can in fact go live in the forest in your underwear if you really want.
Governments build roads, so governments are.
and we the people only vote for governments that take care of our roads, so we are responsible, not somebody else.
Governments also are the greatest destroyers of roads; Primarily to deny their use to other governments. We the people want clean functional roads, we don't want to bomb anyone's roads, and yet the government does. Curious. Almost as if government doesn't care.
Except sometimes we do want to. It is easy to blame the government and they certainly do not always follow the will of the people, but acting like people are never supportive of war is dishonest.

No, that's humans.
1) Animals make use of roads too, makes it easier for them to get around just as much as humans. For example coywolfs spread along the rail lines from Algonquin Park in Ontario to as far as Downtown NY. Seems like Fences are the bigger problem. Preventing some migration routs.
2) Animals are relatively quick to adapt. It might take a few generations but they will. There are street dogs in India that live their entire life on the busiest streets and manage avoid getting hit. Kangaroo's, Deer, and squirrels learned to avoid roads too for the most part.
3) While human development is bad for some species. Others thrive around humans. More Deer live now than ever before, for example.
4) Not really convinced that we have a net negative on the total biomass of animals on the planet. Lots of evidence that CO2 promotes plant growth. Greening the planet. More trees, would equate to more forrest habitat for larger animals.
