It looks like Berlin took some cues from Breaking 2 w/ a dotted 'tangent' line throughout the course, and it looked like the cyclists rode ahead and grabbed bottles for him off the tables. I thought that was part of what made the Monza race illegal?
Berlin has had these dotted lines since at least 2007 (I ran there).
As for the bottles part, they are only allowed to hand him bottles in the official drinks stations and he has to take them (they have to stand on the side of the road and can't cycle next to him).
