As Americans, we pick a place to live and then figure out how to get where we need to go. If no way exists, we build it. Roads, arterials, highways, Interstates, and so on. Flexible and distributed transportation networks are really the only solution compatible with that way of thinking. Trains, which rely on a strong central network, never had a chance. We were destined for the automobile all the way back in 1787, when we first decided to carve up the countryside into tidy squares.
