You just can't have
walkable urban areas if you have one-car-per-adult-resident-and-commuter. The parking takes up too much space. Some people don't want walkable urban areas, and that's fine. It isn't the only model. The problem is that for too many years policies in existing urban hellholes were about accommodating cars and they proceeded to hollow out their cities, dividing neighborhoods with urban highways and throwing up parking lots and garages everywhere. This wasn't the only reason for the decline of urban America post-1950s, but it certainly didn't help.
