In transportation, we are shying away from major new projects like high-speed rail because they do not fit in with contemporary American commuting trends — forgetting the fact that the U.S. car reliance is a constructed one. We spent massively to create the highway network, and the result is that it is now the backbone of most Americans’ daily commutes. There was nothing natural about that process, and no reason to think that it cannot be reversed if we thought differently about our transportation system development. We are adding population at such a quick rate that we could encourage different commuting trends if we want to, but only if we invest the resources to do so.
