The riders main reason for being on the bike is to keep it from biting the other bikes. I wonder what pandomonium is happening beyond the crest of the hill after the bike realizes it's free. I hope the race organizers have a captured female bike in heat they can use to lure it back into its pen.
When it makes it around the corner without falling over though, then decides to win the race without a rider, that's a confluence of several laws of physics and a God who's laughing like a hyena.
