You have to drive several hours in extreme traffic to reach a substantially different housing market, which obviously involves air pollution, climate change, energy cost, road infrastructure, parking space, collisions, and a substantial portion of your life and productive capacity. The same situation in San Francisco plays out in its suburbs, only worse, since a meaningful growth in housing capacity would be an even bigger change for them. There's a great deal of city-by-city, neighborhood-by-neighborhood, unit-by-unit variation, but the crisis is that even the floor is so high.
