Mark, I think karma is an appropriate title. I've flipped a car off one time on the bike. I can't give an exact figure while in a car. Maybe 6 ? My Dad was terrible. I've probably seen him flip off 50 or better.
Anyway, the time on the bike, I quickly realized it wasn't a good idea. Karma indeed. I hope the rider is ok. I've "touched" cars at speed before. I care not to anymore. Once when I was 16 with a couple buddies (all 3 of us riding RD350's) I thought it would be a good idea to pass a line of traffic coming back from the Kenai Peninsula thru the mountains. It wasn't a good idea. I put a 5' boot mark on a white Ford Galaxy with a family of 5. What I will never forget, is how big their eyes got.

I sure don't want to kick one. Road rage and scooters don't mix.
My other touch may not have even been a touch. Launched from the passenger side over a '66 Nova station wagon. I'm not sure if I touched anything other than the handlebars.
