If only there were a way to host damage-less races, like live multiplayer time trials. Some tracks are only worth racing with weapons on so one can roll more.

There is merit in racing with weapons, though. 1v1 or small races like 4-5 pilot races are very manageable. It's only when you've got 2 serious racers and 6 goofballs clustered around them that you're either 5 seconds ahead or 5 seconds behind.
