I don't even know how that thing works, I hope the Japanese do.
"EHm... I need to go to work and my car is on the third floor next to a dozen others, then there's the second floor that's cramped and then there's a few on the first floor...how the hell am I supposed to get it down??? Oh wait....that's why their subways are so packed."
