I don’t think urbanised is a good word to describe that alienation. The urbanism movement has as one of its key goals the creation of more vibrant local communities. It’s more like suburbanism.

Urbanized is a great word to describe that alienation. The urbanism movement is trying to create more vibrant urban communities because of the fact that urban environments are inherently alienating, even if you ignore cars entirely. This is why your original comment was dumb. You are naively fixated on car culture as the source of all social alienation, to the extent of implying that cities would be egalitarian utopias if not for cars.

You're the one who's been talking around me this entire time, I've been making my points very clearly but you're talking past me because you don't want to admit you were somewhat mistaken.

the biggest thing that hurts local community feeling is car-dependent infrastructure.

No. Cities are hubs of specialization, which breeds inequality, which breeds resentment, which breeds alienation. No cars required. Have you ever read a Dickens novel? You think life in 1800s London was all hunky-dory because of the lack of highways and non-Euclidean zoning laws? Like what dude?
