This is why we Americans may be happy to hang out and chat on /c/fuckcars, and try to vote for sane transportation policies, but then also be like lol no I can’t actually get rid of my car.
Every big American city you’ve ever heard of is solid “car” except for the heart of New York. Now just imagine what it’s like for the folks in rural areas or even in the suburbs of medium cities.
This is a pretty sparsely populated country on average, and it’s all designed assuming everybody is in a car. Sidewalks and bike lanes get sprinkled around where there’s room and desire for them.
Actually many European cities would be green as well. For example Munich still has a modal share of 34% cars. However none of the other options has more then that with walking and public transport being at 24% each and cycling at 18%. You could very much live without a car though.
