Still, you can live without cars outside NYC.
I’m currently living in the French countryside in a 3k people village. I do have a car but I barely need it on a daily basis : I WFH or take the 20 min train to my office (currently writing from my train running at 160kmh - 99MPH) and I have a grocery shop at 5 min of walk from my home.
I do have "luck" (well, it’s not really luck since I choose to live there) because even in France/Europe, it’s far from the norm.
But it’s possible and working solutions exists all over the world, just waiting to be copied.
