It’s cheaper to own a car than to use mass transit. When you take all the costs into account (and even ignoring the convenience factor) it’s not really surprising at all:
Anti-car people will argue that the high cost of living in New York City or San Francisco is some kind of anomaly, and that proper government action could magically create low cost of living dense urban areas. I am doubtful. Government regulations usually drive up costs rather than reduce costs (with the exception of regulations carefully thought out to prevent value transference). In fact, the rent control laws in New York City, which liberals think are making housing more affordable, are actually contributing to the high cost of living here. I’ve previously suggested two reasons why dense cities are so expensive: (1) dense cities create transportational and space inefficiencies; and (2) dense cities attract liberal voters who elect liberal politicians who enact dumb laws which increase the cost of living. Maybe there is some third or fourth reason as well. Until someone can demonstrate a place where it’s reasonable to be carless and it doesn’t cost a fortune to live there, one has to assume that such places are inherently economically inefficient.
The arguments against cars and sprawl are aesthetic (and elitist), not economic.
