- Suburbs times 100. Now, the suburbs would be even less accessible as they wouldn't even be connected by roads. Coincidentally, they could be anywhere, which would spread out utilities and make them even more inefficient as they are now due to sprawl.
- Much, much more expensive, both due to the complexity but due to insurance. Already cars are deadly and destructive, flying cars would lead to all sorts of accidents and property destruction given the difficulty of driving them especially by non-professionals. This too would probably be normalized like automobile destruction is but the actual cost will still exist and need to be subsidized by sky high insurance premiums
- Further destruction of cities. Now, like wide streets and highways that demolished neighborhoods (often black and immigrant communities), we'd see calls for destruction of tall buildings for "the sake of safety" due to the common place destruction discussed earlier. Streets and walkways like sidewalks today would fall into disrepair, trees and monuments would be cut down or removed for safety, and so on.
Then again, I don't think we'd get that far due to climate change, but this is just based on a historical understanding of what happened to the US since the 30's. I can see a much more atomized and disconnected society.
