I've been racing AI for a bit and I've kept on beating them. I've heard that u can change the racing line of the AI but how and can they use better setup's.
Yes,starting with patch Y. I remember that I started LFS with patch X and I recall message where was something about that AI learned something (can't recall correct message though) when running them.
Tip to OP - if AIs are too slow,make your car slower with intake restriction if you want some challenge!
