The weak have to stand inside while all the studs (and wanna be studs) traveled on the Foot Board.
It is also used as the diving platform to exit a bus traveling at 20 kmph or more. Accomplished footboard surfers can board or get off a bus at fairly high speeds - even when bus is turning and there is no bus stop.
