In my opinion, absolutely. It seems the motorbike crashed into some idiotic hooligan, it was an accident, a race incident, in which riders had no involvement whatsoever, but have been clearly affected by it. Froome Porte and Mollema had roughly 1 minute over Quintana's group and they were nearing the last kilometre when the disaster happened. This is a historic disgrace for the Tour de France, and anything not being Froome in yellow tomorrow would be an even bigger disgrace.
Quintana was going to lose 1 minute and a half, ended up losing half a minute only. I'm sure he has nothing to complain about today's decision. I mean his Giro victory was already stained by his cheating, 2 is way too many. I just hope the crash was nothing serious - this could be a turning point in the Tour.
