I did fall off last week, on the ice. The last corner before home, on an ungritted side-road damnit.
Hit the ice, I still had balance, but no steering or brakes, realised in an instant I was in trouble and would be comming off. Simply had a moment to decide how to come off; keep going and hit the kerb? No thanks, dont want to flip over uncontrolled. So I just put my foot down and fell sideways, bit of a bump and dead leg but nothing serious.
