In my opinion if somebody gets to know the AI is race-able. If he start the turning phase, he doesn't give you space (a good example: Australia - Melbourne second last corner).
The AI handles player in other way. He tries overtake what against other AI will not do. Sometimes they try in stupid places, where it's obvious they can't overtake you, and you just lose time.
In practice and qualifying there is a new problem. If AI not on their hotlap, they let you pass, but after you passed they start push again and sometimes they try to overtake you (especially anoying if they are in a faster car). And if you want let the AI pass (on his out/in lap) you can't because they slow down too. I tried to brake hard, it sometimes work. Also if they are on his out lap in sector 3 it isn't a problem.
I think overall the AI is good, I enjoy racing against them, maybe they just need a little refine.
