ok, just had a look at 0.7d. Tried it with Tatuus F3 and Formula Isi. Two problems: - AI is running sometimes over the sausage curbs at first chicane when going two-wide. Corridors are, as far as i see, set as good as possible to keep the AI away from the sausage curbs, but sometimes they decide to hit them still. Should be not that big problem as the race mostly continues. - biggest problem is the AI bumping other cars because of ignoring/not seeing them. So you have mostly one car that hit another car with high speed from behind instead of braking or reacting to it. Other cars behind also ram into the accident. This issue came with v1133 and is not fixed till now. You could see this issue in lap 1 also on other tracks with a full throttle part and then a hard braking zone like Monza, Avus or Indianapolis GP. So i fear there is nothing i could do. Recommendation is as said above to use v1132 as long it is possible. v1132 has an AI that is able to react.
