These photographers contribute to accidents on Dragon as well. Riders want to look cool and get over theirs limits. Also, looking at the photographer they are going wide into the oposit lane.

. No such a show-off mentally.
As for this vid, it's hard to judge from it, but it looks like something on the road that contributed to loose the rear...
