> Oslo tried to ban cars, but there has been a huge backlash, without the right sort of support some of the most vulnerable (i.e. people with physical disabilities) just cannot live successfully in cities.
The backlash is pretty dishonest, though. The car-free area (a small part of downtown) will have more handicap parking spots than it does now, sidewalks are being improved so they're larger and universally accessible, and the disabled benefit from cycling infra too—I see people riding mobility scooters in bike lanes in Oslo, much as in this video, but not so many specialty bikes: https://www.youtube.com/watch?v=xSGx3HSjKDo
It's generally the Joe Schmoes who cry "but what about the disabled" and "but what about people who NEED to use cars for their work?", blithely ignoring the points above, and the fact that trade and service unions welcome the change because they'll be allowed too, just like in pedestrian streets, and they'll have an easier time of getting around when they're not trapped in car traffic by people who drive through downtown just because they can and they don't want to use the tunnels.
Which means more wilderness & biodiversity, or more farmland, depending on the area. In Oslo you can ride the subway to the edge of the forest & hiking trails. Some people want to replace the hiking trails with suburbs and detached housing. They're not popular people.
Packets can arrive out of order, yeah. TCP includes ordering information, so lost packets can be retransmitted and in the end everything'll be in proper order.
As for UDP, I'd tell ya a UDP joke, but get it you might not.
