DKR is about the only racing game I STILL can't beat. I'm stuck on that last race where you have to race Wizpig (I think that was his name -- if not, meh) on the rocket. I'm terrible with the plane.
And DKR is the model racing game in my mind AI wise, especially because of the rule where the racers that are way behind STAY behind. I can lap everyone in the hovercraft races (I am amazing at the hovercraft) and the game won't send the 2nd place person up like in the MK series.
Actually, there's a semi-obscure racing game for the N64 entitled "Snowboard Kids" that had the single worst AI ever. Far worse than MK, to be sure. Essentially, the game sends a CPU-controlled character to wherever you are on the track, no matter how far ahead or behind you are. If you gain a half "lap" advantage, it'll be gone in about 5 seconds. If you fall behind by a half lap, the CPU-controlled character ahead of you will have about 10 accidents in a row so you can catch up. Essentially, it is a coin toss as to who wins.

"Super Mario Sunshine is an overhyped, boring kids` game with a fruity name that got higher ratings than it deserved."
