Yeah, this is not a good thing and I, too, would have been offended and scared by this type of behavior. I have only had a sportsbike blow by me one time and I was in my truck doing about 60 mph. I had no idea he was anywhere near me till I saw the blur on the road beside me. Took me a few moments to realize just what had happened. Maybe it's not just the rider though. I've never been harassed by a rider on a Vespa. HaHa
