I have noticed that with the newly released Spa, the AI are crashing quite frequently in various corners. Eau Rouge, Radillion, Les Combes, Turn 11, Pouhan and Blanchimont are the most frequent corners. The cars that struggle the most with AI are GT3, all Tatuus cars, LMP2 and LMP3. I put together some (crappy sry) clips of what I had recorded previously. These issues aren't hard to recreate though. Do an AI race with any of them at Spa and you should see the issues. I use the heavy rubber real road for each clip.
