I saw a couple of the riders, including the stage winner strike out at the runners, Richie Porte was nearly taken off by a flag and even one of the motorcycle cameramen could be seen easing a 'spectator' off the road and straight into a wall.
It's always happened, and riders (including stage winners) have been taken off before now.
ASO and a bunch of the riders have been using social media to try and reduce it, but those guys we saw yesterday have been up there for days, drinking and partying, so the results are pretty inevitable.
I saw some of this in the Exmoor stage of the ToB last year, there is a great photo somewhere of one of the riders looking across at a fat guy wearing a mankini running alongside him, the look on the riders face is superb.
You can also get really cool situations like this (again from the ToB, but the Welsh stage): http://3.bp.blogspot.com/-Vug4ILgr3Hw/U ... 0/epic.jpg
The boxer was Luke Rowe's brother and the rider was Gediminas Bagdonas.
