Segway Racing?

I first learned about Segwag Polo from show My Life on the D List.  This got me to thinking if anyone ever tried Segwag Racing?  I have played with the idea, but what kind of regulation would the race have?  How long will the race be and what shape the track will be.  Also rules for crashes and infractions like if a driver punches another.  It was a crazy idea and Segwags aren’t that popular.
