I noticed massive problems with the AI at the Norisring. Hitting the walls, driving slowly or sudden braking at the straights. At first I tied to do a race with a full field (AI:100) of WTCR19 AI's for 30 minutes. I started at the back of the field, after 30 minutes, I finished first and only 2 other AI's "survived". After that I did the same but set the AI to 104 but nothing changed. Also after 30 minutes only me and two AI's survived. At the end I tried also again a 30 minute race but with only 11 AI's and set the strength to adaptive. But with the same result after 10-12 minutes all AI's were retired.
The same with DTM! Ai are constantly hitting the walls and each other! I went from near last to second in a couple of laps, really breaks the immersion
