Why does the US need to have traditional cities? I grew up in a high density city overseas and I can see the appeal of both types of city. I personally prefer low density, car centric cities (obviously we need to finish solving the emissions problem from cars, but that's separate).
We Americans are a nation of people who spend the vast majority of our waking hours inside. We go from building to building via car isolated from the world and each other. It’s an enormous waste of land and resources since every building has to have its own parking. Most parking lots at stores sit empty most of the time. It’s unhealthy that we walk so little. It’s unhealthy that we interact so little with those aroun…
Low density suburbia can, and usually has, plenty of walking spaces with a ton of nature around. I lived in multiple suburban neighborhoods and I was always either within a short (and easy) drive to a park or had great walking areas in the neighborhood itself. Contrast with high density, where you have to deal with pollution, noise and potentially crime just to walk to a park (and in the park itself)
Regarding "fear or interacting", in my experience I have a lot of more interactions, of the cordial and polite kind, with the few neighbors I have in my low density area than I've ever had when I lived in a high density city where you can feel like an ant in a colony.
