On the shuttle back from work this evening, Peter was handing out BART cards like candy. I noticed that he had an unusual card:
Getting to the airport via public transit is too complicated. BART ends, but then the AirTrain begins. The AirTrain takes another several minutes, but then inconveniently drops one off in the middle of the parking structure; from there one must walk through zebra crossings and around structural pillars (how would someone in a wheelchair negotiate this?) to get to the terminal. From there, through a subterranean passage. And then, finally, into the airport: at least ten minutes *after* getting off BART. Similar systems in Zurich, Geneve, London, etc., etc., ad inf. all let off travellers in the terminal building itself.
