Honestly I can't remember why that happened, it was just so weird.
if you're asking about ullrich, it happened because (IIRC) ullrich wanted to ride the course one more time, at speed. he was drafting off of the team car, and a car with a trailer pulled on to the course. the team car slammed the brakes, because it would have t-boned the other car.
