Why haven’t they tried this at E3? Because cycling doesn’t work the same way it used to since Pogacar, MvDP, and, in some situations, Remco have taken over one-day races. Simply put, 50–80 km from the finish, the peloton is no longer capable of keeping up with solo attacks from these three, even when there are 30 riders together. Even if Politt or Wellens managed to break away (which they wouldn’t be allowed to), MvDP would still easily catch them.
Pogacar’s advantage on the cobbles isn’t so much about bike handling as it is about positioning, where he is probably the best in the world. The only time he misjudged his positioning was at this year’s MSR. The idea that he would look foolish if he got dropped by MvDP at the finish while still ending up on the podium just proves how different the standards are for him (which is normal when discussing the GOAT). If MvDP were the one getting dropped by Pogacar on the final climb at Il Lombardia, everyone would be singing his praises.
