The lead motorcycles need pepper gel spray cannons to clear the route for the cyclists.
"Fans" making themselves the show have been a menace for decades but it's getting worse. I kinda miss the 1960s with the 50 year old, 50 lbs overweight dudes in sport jackets jogging alongside the riders on the steepest mountain stages. In retrospect that was the least bad part of grand tours as participatory performance art.
