Lets see, first I was 12 years old, riding my bike at full speed with a building off to my right, getting ready to hit a ramp, just as I make it to where the building stopped, a maintenance truck pulled out in front of me, I ducked my head down and thankfully my helmet absorbed the impact. Left a huge arse dent in the guys truck. Scared the crap out of the poor guy...
Then I bought a sportbike... :P
The closest one was some oblivious cager pulling out in front of me, going about 50mph and just stopping in the middle of my lane, I freaked and hit the brakes. He saw me at the last second and gunned it.. I barely clipped the rear bumper of his car, just enough to throw off the handlebars and cause me to fall down.. slid a good ways down the highway. Just want to thank the cow(s) that died to allow me to slide down a rough asphalt road at 50 mph and get up a little dazed
And to my parents for raising me with enough sense to wear leathers, a full face helmet and gloves when flying around on an engine mounted on 2 wheels
