will the AI cars stop bumping into me me when I am driving? I understand the cars now can do the pit in, but that's the only improvement? For me it's more important that they're not as dumb as a slice of bread, living their own lifes, bumping into me here and there as I pass them or they pass me.
You can see them slowing down on the straight if they do this, which is a shame. Definately an improvement though!
Give it some time, and I belive it will be even more improved.
