Rally: For certain categories like (FWD H2, R2, Group A) the AI seems to be way too fast! They are doing World Record times. In group A, it seems to be different for each location (In new zealand there are no problems but in Poland, its nearly impossible). It's nice to have a challenge, but the AI in certain catagories need a fix.
Rallycross: The cars that are not in your race are way too fast and the ones in your race are too slow.
I don't know if anyone else can relate with this, but those are the problems that I seen.
