thats a good point i've seen videos where people just stand they're going 'oh my god' or 'is he okay?' its like does he look ok? i think the best you can do is where a helmet but be ready to crash so you can land on your arms and try to roll out of the crash, worst thing thats gonna happen then is cuts, bruses and at worst a broken arm. i see far too many riders that hold on to their handlebars when they are crashing, as if they can ride it out.
