I think this stuff is too common in the united states. I think of bart/caltrain/amtrak/busses/etc. It seems like it was only recently that bart reached an airport.

sort of reminds me of shipping before container ships, where you had to have freight forwarders to get stuff through the morass of trucks, trains, and ships, each with their own politics/unions/finances stepping in the way.

The politics of different means of transportation, with different systems just runs into enough of these barriers to self-limit their own use. and we end up being a nation of cars.
