And there you can see how close they are watching Cav --->
A second video was posted, however, which showed that that guy was just a member of the tifosi, and what looked like Giro accreditation was probably a freebie from the race caravan. As has been mentioned, the commissaires and riders can't control the fans. When I was on the Urkiola last year there was one fan near us who would sprint as far as he could up the hill pushing stragglers, then run back down to his position and wait for the next lone straggler (he only did it for guys who were on their own) and do it all again. The commissaires let it go. He's not doing anybody any harm. If he was prejudicing the results by doing it to that extent for front runners, they might have done something, but ultimately giving a few lone stragglers a push has little effect.
You could argue that keeping Cavendish in the time limit does prejudice the results, which would be a fair point, but at the same time, Cavendish hasn't been expelled from the race for it, and it isn't something that Sky or Cavendish can be blamed for (not like it was holding cars etc). Not unless Team Sky have a bunch of guys that they plant among the tifosi on every climb to push Cavendish along, which sounds pretty far-fetched.
