Surprised no one mentioned this, apparently a woman w her back to the cyclists held a long nonsensical sign [in French and German? (which says roughly "Let's go, grandpa and grandma!")] w her arm sticking well into the road, and the result was havoc and destruction. Just wow...
She apparently then took off and now the police are looking for her and the organizers, etc wanna sue the crap outta her. Some ppl are speculating that a gambling syndicate intentionally set this up and that she's not even a woman haha.
