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. Regarding the  generating the replacements

In Porsche Test Track I have gone so far that new bots are generating in front of me. You can drive normally then suddenly the bot warped in from outer space immediately in front of you.

Quite funny to see that shortly after that they got overtook and have to warp back to outer space.
