I noticed that also. Actually a bit too much, as if it was more for show than speed. In fact in many cases it seemed to slow them down too much. Obviously this video is from some sort of expo/demo event, not a true race; lots of loop-de-loops, circle drifts, donuts, and other showboating. Various classes from all eras, plus the course wasn't typical of most rallys, not to mention more camera coverage than normal. So the 'flicks' were likely part of the show. Lots of fun to watch though.Lots of Scandinavian flick being used.
I recall there is a major rally event in Latvian every year? I imagine there must be a few local teams based there.First car in video before pressing play is with Latvian numberplate
