Anti-Pattern: Opponents adapting their speed

Unfortunately I'm not able to give You patterns, but I would like to name an anti pattern. Please do not try to adapt the speed of the AI drivers to the one of the human player. The idea behind this is to create fair racing conditions for amateurs as well as pros and to abandon the need of multiple difficulty levels (and their implementation).

However, what sounds good on paper turns out to be awful in practice and the MotoGP series failed miserably at implementing this behavior. It ended up in the opponents driving at 5mp/h when you stood still for a couple of seconds and the impossibility to tell whether you've improved in the game (very bad feedback wise)
