Every hit lands somewhere. And the car remembers it.
The nose takes the radiator and the engine, a corner takes the wheel, a hit in the flank bends the steering. Bumpers, bonnets, doors and wheels come off and lie in the arena for the others to drive over. Engines smoke, misfire, boil and burn.
It is an arcade derby: the cars take a lot, the walls hardly hurt, and the car that drives in takes far less than it gives. A big enough hit rolls a car onto its roof; it rights itself and comes back for more. Back into them and keep your engine: the oldest trick in the field.
