There's absolutely a surplus of motards in a race. Apart from a gazillion photographers (why, just why?), there are also the commentators like Voeckler and Vangramberen on French and Belgian television. Not just do they barely add anything to the race, they also take up space.Just use drones, what is the function of two motors there? One is for tv, what’s the other one doing there?
Remember when Flecha was about to win Gent - Wevelgem in 2005, but an already beaten Nico Mattan was allowed to take a seat on the motor in the final kilometer, got to close a 15 second gap in the blink of an eye and subsequently won? That should have been the moment to cut into the amount of motards in a race, but here we are, 18 years later, and it's still a problem.
