Is this theoretical advantage that always exist? I mean; the instances at Strade and MSR that folks claimed motos impacted the race was clearly in error. They aren't dragging anyone up a 15% gravel climb raced at 17 km no matter who is rooting for them.Because he is by far the strongest rider of them all. We all know which riders are the second best. And yes, it's a problem with those, too.
That's exactly what teams like Quickstep have had as a tool in their race tactics. Attack and use the motorbike. Why the heck is this great for cycling? Why give the strongest teams and riders an extra advantage?
There are less motorbikes in front of the chasers, because the leaders are the ones that are most interesting to follow for the camera men and photographers. But even if there are motorbikes helping the other groups, it influences the race because it reduces the drag difference between the groups. If a group of five riders are chasing a group of two, it would normally be an advantage for the big group, but if the two-man-group have two motorbikes within a few seconds ahead of them, it's like they are sitting at the end of a peloton. This is probably one of the main reasons why we so rarely see favourites being caught in the last 20 kilometers of big races these days.
It's true the race leaders have a moto in front of them because that's the security for the lead riders. Most of the time the press is behind or alongside. If they are in front of a lead rider like Pogacar there is an official moto there as well. Today at Amstel the images were almost always from behind Remco's group in the last 50km.
