Haven't seen this mentioned here so I thought I'd bring it up.. the other week at the Lausitzring Gary Paffett was (wrongly) given a stop/go penalty during the race for overtaking under the safety car after he stalled on the dummy grid. After a protest from his team, the organisers scratched all points from that round.
Does this set a precedent of some sort? To me it seems like annulling a stage of the Tour de France just because a cyclist hit a spectator or something.
