I hope no one will think it too unorthodox if I respond to my own comment just to add that given these constraints on land use patterns it’s obviously the case that Americans choose to drive automobiles. It’s fairly common to hear people describe this, too, as another kind of “revealed preference” for driving over the alternatives. But it’s a revealed preference in the environment as it exists today, which is the only environment that’s legal. If people were allowed to build other kinds of environments, then they would build other kinds of environments and in those other kinds of environments they would make other choices about transportation.
If you only look at people on the beach, you’ll find a revealed preference for flip-flops. But in other kinds of environments, people wear other kinds of footwear. If you only looked at people on beaches, you’d draw some funny conclusions about what people like to wear on their feet.
The big takeaway here is that the suburbs are the result of big government social engineering on a massive scale. You really can’t look at anything about land-use or transportation and conclude basically anything useful about “revealed preferences.”
