None of the other skaters in the video got in the way of B&S when they were rehearsing segments of their program. The practice ice belongs to everyone. The only thing is, the team whose music is playing has the right of way. When you see them coming you are supposed to get out of their way so as to avoid collisions, as the other teams did in this video.
But these teams were at the center of the rink! When B/S's music played!!! What about 'the rule'????? They were shamelessly breaking it!! Multiple times!!!
Sorry, just kidding. My point was that it happens all the time. Sometimes it's more serious, sometimes it's less. But NO ONE doing it on purpose. Did you see V/M's dangerous moves at 2:52 of the video? And Dima had his back to them, so he didn't even see them coming.
