I actually think that sometimes he does receive more help from the motos because of who he is, but not for the reasons that some people here are suggesting. I think it often comes down to the fact that he's Tadej Pogacar, and the TV directors, race directors and photographers want to best shots of him, especially when he's doing some sort of crazy attack. I think that's why we got that ridiculous convoy of motos in from of him and Pidcock on the Poggio, because everybody wanted the best shots of him attacking MdvP.
Escape Collective had a really interesting article about moto draft a few weeks ago. I know it's subscription but I think you can make a free account and still access some articles. They made some really interesting points about moto draft. They talked about lot about just how much benefit it can offer (a lot!), but also explained why it can be so hard to stop motos influencing the race completely. The most interesting bit for me was how hard it can be finding good moto pilots - often they're police officers taking time off from their regular jobs - and how hard it can be for them to make in-race judgements about whether they are too close. Obviously it needs to come from the race directors, but it's got to be applied to the photographer motos too, as it's not just the camera motos that are an issue.
