I've only had one really scary moment (so far). It was on my BSA towards dusk, in a light drizzle on a two-lane, small town road. I was stopped to turn left, and a woman never saw me and launched me and the bike about 10'. I landed upright, did a couple of major tail wags, went down and spun 360 with my ankle as the fulcrum.
Now, here's the good parts. First, I had just started to go forward, so I was moving and I think that absorbed a lot of the energy. Second, she was a little old lady driving slow in the rain. Third, my boots and rain gear let me survive with very minor scrapes and a sprained ankle.
This happened in 1966, and the woman was driving a Renault Dauphine (anyone remember those?). Her grill was caved in, her radiator pierced and leaking, and they had to tow her car away. After the cops did their thing, I pulled the bent fender away from my rear tire and drove off.
