Last weekend, I'm northbound on Interstate 75 between Dayton and Cincy... in the centerlane doing about 73 mph. Two of these yo-yo's flew past me STANDING ON THE REAR WHEELS only, one in the left lane and the other in the right. They had to be doing 100+ mph -- They each had passenger holding on for life and limb -- no helmets, no turn signals, NO BRAINS.
Good God almighty.
I used to road race at WERA sanctioned events in the south-east region during the late 80's. I regularly raced at speeds over 100mph, sometimes nearing 165 depending on the track and bike. Fastest was a 1986 GSX-R 750 superbike at Road Atlanta, probably hit 165 on the back straight. I did this for several years and got pretty decent at it. The speed never bothered me because of the conditions. Safety, equipment, etc.
I also used to ride fast on the streets. Sometimes at speeds over 100 mph. One day I was in the Wash DC area tooling along on my 1998 1200 Sportster on the beltway at about 70mph in the middle lane. Two sport bikes passed me on both sides at an incredible speed. I'm guessing they were doing about 150mph. It actually scared me because I never saw them coming. That one incident was enough to make me realize how truly insane those guys were.
Speed has it's place. You can argue the legitimacy or lack of legitimacy of that speed on a track if you want. However, there is no argument. That kind of speed doesn't belong on a street - EVER! Who cares that the nut is risking his life? OTOH, most of us care that the nut is risking our life.
I personally know of one incident where a motorcyclist T-boned a car at a high rate of speed. It killed the motorcyclist and his passenger, plus killed the peopl in the car.
