There are many of times the AI grins against me and tries to get me to the wall. All you do is tap your brake once then floor it and hit the boost button. You will never have a problem doing it this way. My audi TT drives better then tier 2 AI cars. Hit the brake around corners and its all good. Especially with the arcade style control there are countless times going down a hill at 150+mph I tap the brakes then turn and floor it and I stay on the road. If it was any other game my car would hit the wall all the time.
