hahahahaha.... yes !  it took me quite a while to figure out that the doors are not manually opened but instead are electric... you can actually open them with just one finger if you touch the right sensor spot (the little picture of the hand).... that being said there apparently is also some mystery component that the driver has to unlock from the front as well.... but usually i do enjoy when 4 or 5 riders all yell "back door!" at the same time to help out some poor unfortunate soul.
