I know that it is still wip after 5 years, but with last build of sim, it is worse. Ran against AI at Matsusaka, it rained, AI waited too long to change tires, when track was almost dry they decided to change to wet tires (may be mod or track related), but to do so, made the whole lap before entering pits at slow speed not on the racing line. Cheers.
I saw a new behavior that in practice the lap before entering pit, the IA are using the left lane only Are you saying that they do that on race too? If it is, thats a serious bug Thanks
Also in a wet race the AI will change their wet tyres every five laps. Sometimes they will stop for a fresh set after only one lap. I hope this gets fixed in the next build.
