I didn't mention small towns. My concern is primarily with the
large cities in the United States that have functionally useless or second-class public transportation systems. Places like Phoenix, Houston, and Los Angeles that collectively house tens of millions of people in sufficient density for public transit, but lack effective systems due to poor planning, corruption, and lack of creative problem solving.
Of course there are use-cases for cars, nobody suggested that there aren't. The problem is that the United States in particular has assumed that every transportation issue is best solved with cars.
