I’ve spent time looking at a map of my city, and it’s pretty easy to see the transition. The older streetcar suburbs have streets on a grid, and alleys down the middle of every block. The post WW2 areas are all widely separated and full of cul-de-sacs, and the alleys are gone. Walking anywhere in the older areas is easy, though a lot of the amenities like mom and pop stores are now gone. Walking anywhere in the newer areas is pretty much impossible. The streets don’t connect and there is nowhere to walk to.
