Tron Lightcycles, in Real Life

Bad Panda! No Bamboo for you! In matters of importance ACs will not be responded to. Want to say something critical,OK

I've seen variants of Tron that add a Go-like rule... if the other person completely encircles you, you lose. That would encourage the contestants to try to pedal faster than the other guy, which could be pretty entertaining. (this could make teammates and tunnels more interesting as well)
