BART entrance has some errors. The escalator is mapped backwards: it always goes up, from the inside of the station up to the plaza (not down or backwards or whatever the current tagging is showing). There is one escalator and two stairways, not three, and the bike ramps  (two of them, not one) are part of the center stairway, and not a separate fourth way. The area occupied by the stairs/escalator should not have an additional highway=pedestrian tag, which implies (incorrectly) that someone can walk through this area without falling from a great height into a deep hole.
