BOTH cars MUST leave for it to be a race. If you leave and I don't move, it's NOT a race. If you let me leave and don't move, it's not a race.
I'd get into other terms, like a car, the break, and the clear, but I'm sure you wouldn't understand. And if they pulled that non paying crap around here, the noise makers come out.
Its a show about street racers, not grunge racers. Thank God for that.
