I am halfway through the cars on this version
Currently only 3 (both Audi and the Lambo) I didnt manage to finish at all, they are eating tyres too fast.
And only once did I not win, which was the Ford GT LM Spec II Test Car
Other players definitly are faster than me, and maybe some cars just dont fit my skills, but other cars were comparitively fast and others really slow.
The fastest AI time I have seen would have betten me quite often.
But there are ways to keep Rubilar behind, the AI will overcommit, and when you force it a few times, it will make him force to take an early pit and maybe an extra pit. See videos below.
