I've agreed to so much stuff on the internet it is pitiful. I bet 90% of people or more that see an I agree box or button just automaically check it and go on. I know this is what I do.
I remember one time I didn't agree..... that sucked, so I had to go back and agree to get my software to work.
on the wrecks, none really, but I did turn my shins to a bloody mess with some platform pedals.. I have since ordered me some clipless pedals so the worst crash is probably yet to come.
