Inaccurate & skewed AI

Ive played nearly 700 games. Scoring is inconsistent and the game is definately skewed toward AI players winning. In race mode, once an AI players score drops below a certain point, they suddenly have a winning streak. Also the same thing happens in reverse when I hit my high score. Ive hit the same high score 7 times and suddenly loose several thousand points. The game could be really cool as it has a realistic feel to it, but something is not right.
