those are all great vids!
That first one with Doohan made me squirm a little. I can remember pretty much every crash I've had in the street, and a lot of the crashes I've had in the dirt, and the vid made me replay a bunch of them in my head. It reminded me of something that the all have in common. Watching those riders slide toward the bus, or the park bench, it was amazing to me how much time there is between when your first loose control and when the impact is. Not a lot of time on the video, but it seems like an eternity when it's you that just had the get off.
Next time you're on the street, just glace over at the parked car or tree or whatever is just head, and imagine jumping off the bike right there.
It's not just 'racing' in the street you have to worry about. Most of my street accidents happened while I was all by myself, just doing something stupid, or not paying enough attention.
Pass that vid on to anyone you know that rides. Better to think about it while you're fapping at the computer, instead of while you're sailing through the air toward a tree.
