Did you see that stuff that happened today?
Guy tossin' his helmet, more like tryin' to clock the driver who wrecked him through the window net as he passed. And this other kid ran another guy to a stop against the side after he "accidentally" backed it into the wall. It is sort of like where they charged the NHL player with assault when he swung for the head. Even with a full-on cage, it is not going to feel too good for a long time possibly life when you go from really fast to dead stopped in a brief span.
Racing is dangerous enough without people trying to hit you, they do enough of that on the streets. How much does one of those cars cost anyway?
