I've always wished for something similar: autonomous car racing. No human drivers. No remote controls. Just program the cars before the race, and let them go. Maybe even load the cars with mild explosives so they go BOOM when they crash.

(Linking that one as it's the first in which any of the teams completed the entire course)

Absolutely love this idea, it sounds very fun
