The Pro racers, can be explained in a similar manner as the Austrailians. The Aussies began, as a bunch of outcast prisoners from England put on a deserted island, and they're a wild bunch. Did you know their biggest sport is DragRacing?
That's what we PRO racers are. We're outcast from the Queen(NSCA), and we're a wild bunch who rebelled and a new org was started.
