Currently Racetrack% bans vehicle thrusters, which makes sense bc they change the scene dramatically. But I think there's a lot of cool things you can do if you're able to use vehicle thrusters and are able to leave the track- I know in messing with this myself there's a tradeoff of thrusters vs. the car's handling, as well as different routes to take / what sections of the track to skip. There's some strategy to it beyond "let me throw 100 thrusters on here and see what happens"
I would define the rules like this (borrowing heavily from existing rules)
- Use only one car
- Cannot modify the track / checkpoints in any way prior to the start of the run
- Must trigger all checkpoints
I hope I'm not coming on too strong- I have no idea how hard it is to make and maintain a category, or what else goes into that. This is just how I play on the track and I think it would be a cool category.
