Help Name Andrew's New Game

Andrew invented a new game this weekend. He hasn't told us all the rules yet, but I know that it involves at least two people and two push toys (lawn mower, motorcycle, car). Each person drives their toy in a crazy combination of racing, playing chicken, backwards driving and bumper cars. I'm not sure how you figure out the winner, but based on all the hysterical laughter I think it's Andrew.

These pictures are a little blurry. We are so fast that no camera can possibly capture clear images of our new game.
