This question is in the realm of not having electricity. Can we live without it ? Yes, but very few people would and it makes life very hard.

It sucks that places are too reliant on cars and I agree we need to do more to help those who can’t drive. But we still need cars to live modern life. Especially in semi rural areas.

First thing I’d do is tax the hell out of or outright ban massive trucks and Suvs. If you can’t prove its used for work, 150% or more tax on it that goes to public transport, and your insurance costs 10x the amount of a small car, because you’re a danger on the road. That right there would get us a shit ton of public transport revenue from all the douches in the US driving massive trucks they don’t need that endanger us all.
