no worry i am always racing off line against AI as well , i will spend time to find a way to correct it , most of the time i try on kunos track to avoid some track mods which can have themselve pb with ai lines !If you want to help, I suggest you to put the whole GT 4 pack on Jarama_2009 track, the 2022 layout, for example, and let the AI to drive. In the 8 curve (a hairpin like curve) some of the cars goes off the track in every lap if the road is free in front of them, piling up in the sand. The idea is that the cars, in this type of curves, doesn't break enough, or take them too fast.
I hope I didn't give you too much work, but it's a shame that such a nice car package can't be played in a custom championship. Thank you.
thank you for report
