I had a lot of fun terrifying a Hummer by riding my Yamaha sportbike 4 feet from his rear bumper with my bike sitting right on the dashed yellow road line. I could see his consternation grow into anger as my bike and I sat squarely framed in his gigantic side view mirror. He gave me many fingers to which I just gave the universal hello on a sportbike: lift two fingers of the clutch hand( that’s left to you non-riders) into the air and a gentle nod of the helmet, my anthracite grey Shoei. I hung there a long time. Several times he accelerated to 90 mph and I held the same position. As he slowed to a steady 70mph I took both hands off the handlebars and clapped, again in the same position where I was framed perfectly in his gigantic side view mirrors. He eventually slowed to 58 mph and I bored of my game. I accelerated past him but hesitated right beside his tinted driver’s window. He did nothing. He did not honk his horn or roll down his window. I accelerated to 95 mph and left him to his life of ornate luxury. Perhaps his civil behavior as I hung beside his driver’s door was partly due to the clearly-visible upper part of my Marine Corps K-Bar which I carried inside my right boot. The grip is distinctive and large. I never honked at him or used the “finger”.
