To be fair, this is kind of a special case- it’s an area where it’s cheaper per square foot to build lots than buildings - but this is also a leftover of the 1960s-1980s. This aren’t done this way as much anymore, at least not in dense areas. You’ll never see this in New York City or in DC for example.
So much of America is so low density that it’s just a different set of issues than in other parts of the world. I went to visit family in West Virginia this weekend and it was literally 2 hours of driving through mountains and woods with no houses or towns in sight- no lots, no decks, no trains, you’re in the middle of nowhere.
