Raising the AI difficulty in these games only makes them drive faster. It doesn't alleviate the main issue, which is that they are programmed to stick to shitty racing lines no matter what. It's one thing that non sim racers have over these games.. the AI are much less predictable.

Put that in GT6 on the highest difficulty setting and the exact same thing happens.
