Take for example a middle-east or european town/city. Lot of housing/buildings built side by side or so close only a person can walk through, within these narrow streets you have also got all sorts of shops (small grocery store, pharmacy, printing shop, laundry, accountant, cafe, ice-cream shop....) and then there are "car" streets, where you park and drive the car through to the "road".
Kids play in these streets without worrying about cars ever coming in, you can walk to most shops in less than 3 mins, people can sit outside of their house and talk to neighbors, go to cafe at the corner to eat with friends, and more.
I once had to go to suburbs for the job, and everything you do, even buying a gallon of milk required 8+ mile drive to walmart. No parks, no pavements, no sense of community, no shops, just drive drive drive... Literally felt like i was stuck in some sort of weird space ship waiting for the landing to destination and had to endure sitting in my seat for meanwhile.
The sad thing is, city design and housing like this affects, mental health, economical mobility, social life, and everything else..
