So lets say just for the hell of it you find yourself at a "circus clown" race, where they run 4 cars at a time. You don't have a real good handle on some rule changes they made, and for now, you're sort of a second tier car. You find in the next round you are up against 2 rocket ship cars and a very close friend, who's struggling a little more than you are. So, in a brief conversation with your close friend an idea pops up. How about your struggling friend leaving on the stage light and fouling out by tons. At that point, one of the 3 cars still at the line is fully aware of whats happened and the other two are not. If either of the two falter for an instant, your second tier car may very well go to the next round, nah, never happen.
