It was until my visit to a thirdworldish country without much decent mass transit that I really understood how absurd it is to build a world where most people, in order to have access to decent jobs and the economy generally, have to purchase and surround themselves in a couple of thousand pounds of metal in order to get around. Sure in a more prosperous country this is a reasonable thing to ask of more people, but it still
leaves plenty of people out. Cars are very expensive. And, no, roads don't pay for themselves.
