Specifically the entry and exit. Who sat down and with all deliberate speed said, "Ok, let's make the entry and exit to a vehicle for rapid transit with steps at a 97 degree slope." "What's that? They'll be most likely carrying 50lbs of baggage up said slope? Screw em, let em pull their lat muscle. Then, oh this is great, for real snickers make the steps 4 inches deep and watch the passengers try to tiptoe in while they wield their Kenneth Cole roller bags up the slope like a Viking barge! What a riot! As Bugs Bunny would say, 'What a maroon!'"

I didn't fall or anything, but that has to be in the top ten worst designs of all time.
