Hah, in the next update opponents will recover faster after they hit another car, so they won't crash into roadside objects that often. Aaand I'm probably going to revert it for easy and intermediate settings because it makes the game much harder.
Not sure how I'm going to get more fps out of the game. Graphics-wise it's not that heavy, but code-wise there is a lot of stuff going on. I'll experiment with some stuff and I'll see what I can do.
Good luck with the motorcycle!
