I forgot about the calluses. I remember a friend you wore bike gloves so he would have softer hands to stroke his lady friends with.
I'd rather break my collarbone than my back. Rolling over the hood of a car, yeah, but I don't know anyone who rolled after highsiding in a corner. Such a move might be beyond the skill set of the average hybrid rider. I'll think about it though, I actually avoided getting tagged this morning by consciously modifying my response to a left turner after the recent injuries of three of my associates by left turners made me to think about the last time I got taken out by a left turner and what I could have done differently.
You make a good point. When I taught snowboarding, I always advised to fall on forearms, held again the body, with clenched fists, rather than on outstretched hands. In snow it's really easy to turn your hands or fingers in a very bad direction, if you try to break your fall with open hands.
I have also rolled off my mountain bike, by holding onto the bars and controlling my endo so that my back landed between the rocks. It's amazing what you can do when you really need to, and it's helpful to visualize your response to possible scenarios.
