I've been thinking about this a bit today, with the new travel power avaiable, we now have something wich has the same speed for everyone, making a racing league possible. Of course, as top speed is fixed, it would have to be more of a pathfinding and obstacle course racing.
Participants and judges forme a league, with say team 1 forming waypoints (and as people are in a league, are targettable for navigation).
I suppose skyway and grandville would be among the difficult places to navigate, with overpasses and underpasses and tunnels. Atlas would be more easy.
Skill would involve finding he best route between skyscrappers etc. to the next nav point.
So far my ideas. Feedback, feasible, fun?
