In Poland it is noticeable how much more often someone who gets "nudged", and goes down, gets excluded...
Kubera on Sunday an example where he definitely was contacted but still had plenty of room to "ride out" the issue, but went down, as, quite probably, he wasn't going to score..
Over here if seems the rider making contact goes (especially during the race after the first two turns)...
Poland seem to have a view that if you leave a gap then someone can fill it and at the last second if you "close the door" and go down it is "your fault"....
Certainly makes for closer, harder, (better), racing...
