In the US and other places with low density, people just don't want public transit if they can avoid it. Its just not going to happen. Are you European? I ask because I constantly have europeans come on here and other places pushing public transit as the solution but people in the states just don't want it and they can't seem to internalize this.
I made this same argument at CCC last year because a presenter was arguing for mandating buses in every country instead of EVs. When I pushed back they trotted out the example of NYC: a single exception whose own subway system is slowly collapsing due to legacy and graft.
Keep talking like this and you'll leave yourself baffled as to why society ends up disagreeing with you. If you look at the voting patterns of people not only in the Americas but also increasingly in Europe, they are already pushing back.
On the contrary, cities everywhere are moving away from cars and towards more pedestrian infra and public transport. Plus, even in the USA, the biggest reason cities like LA or Houston don't have good public transport is that they are gigantic sprawls. More dense cities do have significant public transit options that people use.
