To counter all the whataboutism in the replies to your comment, I just wanted to say that I live in a flat in central Berlin and park on the street, and charging or range have never been actual issues. My car use consists of trips around Berlin and Germany, driving to rural Finland and back, regularly towing a trailer, etc.

This happened to me (luckily not on the highway). Teslas, and probably other EVs, have a pyro fuse which physically severs the connection between the main battery and the rest of the electric system in the case of overcurrent or an accident. When that happens it completely bricks the car (to avoid nasty things like battery fires), and the fuse has to be completely replaced. The 12V system is separate, so things like lights, infotainment & door opening buttons continue to work. The pyro fuse quite literally blows up with an audible thud when this happens.

My understanding is that these numbers (try to) account for actual real world usage rates. Actual emissions will of course depend on a whole lot of things, including the things you mentioned, prevailing winds, etc. Same for estimating grid emissions for charging the car of course - the exact mix of sources is always in flux.

I used the numbers from the Finnish state research centre VTT (http://lipasto.vtt.fi/yksikkopaastot/tavaraliikennee/vesilii...)

This is IMO where the Model 3 shines - it's a great car for longer trips. Comfy seats, and autopilot really reduces the strain of highway driving.

Yeah, there's a ferry from Rostock to Helsinki. However I'm trying to reduce my travel-related emissions, and after crunching the numbers have concluded that the best option would be ferry+train via Sweden, with electric car via Sweden a close second (per head, assuming two people or more in the car). Fingers crossed for that tunnel and a direct overnight train connection!

I'm from Helsinki but live in Berlin, and drive between the two somewhat regularly. For this trip you essentially have two options - either via Denmark and Sweden, or Poland and the Baltics. You need to take a ferry to reach Finland regardless of which route you pick.

The experience and emissions differ pretty dramatically. Intuitively you might think the total emissions would be lower for the Baltic route because of the significantly shorter ferry trip, but this is more than negated by how dirty the grid is in Poland and Estonia. Polish electricity production is about 100x as polluting as Swedish electricity.

The Nordic route also wins in terms of infrastructure. There are plenty of Superchargers as well as non-Tesla charging stations, located at highway rest stops with good services. Making the 1000km+ drive in one day isn't a big deal at all, and I find that plugging the car in for the time it takes to go to the restroom and grab some food is enough to continue the trip.

The city of Helsinki owns about 17% of the residential building stock, not the majority. (https://www.asuminenhelsingissa.fi/fi/content/kaupungin-omis... - in Finnish)
