History is path-dependent. At some point in our nation's history (namely right after WW2), it was decided that cars, suburbia, and the Interstate highway system was the way forward, and not dense, closely packed cities + public transport + more railways. Note that we might not think about this now, but cities before WW2 were often disease-ridden, filthy places. The antibiotic revolution did not really come into full…
We agree on all those points. All I was saying is that people say "cities are spread out so transit won't work" when often the very _reason_ cities are spread out is that they lacked transit, so huge amounts of land were given over to auto infrastructure. It's worth considering that it's self-reinforcing and the causality isn't one-way. Look at a big box store, for instance - most of the land is parking, not the stor…
IIRC, that's ahistorical and getting the causation backwards. American cities used to be denser with more public transit (e.g. trollies) before cars became common. The reason cities are spread out is cars enabled the residents to spread out, since that's what they wanted to do. That established a new pattern of development that makes density more difficult.
