I just found this article on the Cofidis cyclist that was cut off from Demare's very erratic and unsafe lane change
Bouhanni: Demare cut me up in Tour de France sprint | Cyclingnews.com
Demare's move was much more dangerous, so why wasn't he relegated?
“It was a nervous sprint. I was in the ideal position in the final kilometres and I knew the finish by heart. But at 150 metres from the line, as I was on the wheel of Alexander Kristoff, Arnaud Démare cut me up and I touched his back wheel,” explained Bouhanni.
“At that moment it was over. If I didn’t brake, I’d have fallen.”
