It could also have to do with generating the replacements. There are probably only a few spawn points for bots on the track and there may be some logic as to not spawn at certain points based on where the player car is. Its possible that the game is trying to generate new bots at the same spawn point at the same time, leading to the crash, as I doubt the Monkeys would have considered this when programming endurance races years ago.

This is, of course, pure speculation.
