Here i am about 2 hours ago driving in a van with 4 friends, driving down a semi-busy road, two lanes on each side, when this guy on a bright yellow Suzuki or some other street bike (you know the kind i mean) he's going at least 60 or 70 mph, and he pops a wheelie. now he's completely vertical, for a second, and then he loses control and falls back. his back's dragging on the ground at 70 mph, and he's got a 500 pound bike pushing him into the ground. then the bike flies away and he's rolling around (still going very fast), flying into the air, falling again, etc.
now as i look back, his bike is on the side of the road, he's still rolling, and pieces of skin start flying off him. big pieces, whole chunks are flying out. he wasn't wearing a helmet, he had on tennis shoes, shorts, and a T-shirt, and now he's rolling and getting flipped around at 70 mph. anyway, eventually he comes to a stop, he tries to get up, then just falls down. (i couldn't see his body, i just saw a bright red, i assume it was blood... since most of his skin is all over the road).
very freaky. we went to starbucks down the street, and about half an hour later an ambulance arrives. it wasn't scary seeing him fly off the bike, what was disturbing is seeing chunks of skin (or parts of his body) go flying. there's a red stripe about 1 and a half feet wide, and about 30 feet long down the road where he was scraping down on his back with a motorbike on top of him at 70 mph.
so the moral of the story is i'm never, ever getting a motorbike. ever.
