As I mentioned earlier, there are a lot of things about the video above that makes it appear to be a fake, from maintaining an excellent camera angle on the rider & van to the rider reaching out towards the van before being cut off.
Perhaps part of the discrepancy with views is that I'd have no problems with a normal sized vehicle (5 to 6 1/2 feet wide) passing me in my lane on that road at say 20 to 25 mph vehicle speed.
However, once one allows a reasonable pass, then one starts getting those that choose to pass at 60 MPH while driving 8' 6" semi trucks & trailers. And while I'm pretty good at maintaining my line, they scare the bejesus out of me. I still maintain my line on the road
But, I don't want to be in front of the semi that is slow reacting to a bike directly in front of it.
