I was stuck behind a small RV for 35 miles on a mountain road. He was doing less than 1/2 the posted speed (35MPH) and passed up the opportunity to let me and others go on 8 pull offs. (I counted) It was a miserable ride for me, my riding partner and the 12 or more cars behind us probably weren't too happy either..Your mistake was allowing them to ever pull out ahead of you again after you passed them the first time. When I see Harley riders starting to put on their gear, I jump on the bike and leave so that I don't end up behind them. Same applies for RV owners. Don't ever let them get in front of you in the first place if you can.
Maybe that's the problem. That series of hand signals is taught by a multitude of training classes at all levels. No, not all of them are a requirement for licensing but the left turn, right turn and slowing signs were probably on your MC license endorsement eons ago.I couldn't remember all those signals.
