AI is much improved with multiclass overtaking bug fixed for the first time too (only for 2003-2005 gtr2 cars)
I understand if you don't want to reveal this before your next release but it would be really great if you would consider sharing it afterwards. The AI situation in my 1967 sports car game is much improved compared to how it used to be but there is always room for more improvements as the AI are still not as effective as the player in lapping slower cars.
