both ideas are doable if executed right. doing the car selection for each race, see witch one would be better to use and for what type of event. considering to gave a back-up car and stuff. so yeah for me it is not dumb

Trafic RNG is a thing that can be manipulated by using some tech. This is a problem without being a real one. maybe considering testing on some open world racing games, idk. could be interesting tho

It could be fun, but the problem is in this racing game specifically, this type of category would be not adapted. Due to the fact that there is crash cams etc. could be cool in another racing game tho. like Burnout Paradise where one of the rule would be to give a crash limit until getting another license or idk. it's not a dumb idea it is just the wrong game
