Thinking on it I've been clipped by an overtaking lorry once, was lucky I stayed upright - entirely outside my control
I fell over at traffic lights when trying out clipless pedals - not to be repeated but obviously my fault and avoidable
Went in to front of taxi when I made a last second decision to turn into a no entry point - my fault and cracked bone in wrist, so avoidable
Yet I've twice had drinks thrown over me by passing motorists, I've been swerved at deliberately by people I've exhanged words with, I've seen the same happen to others on rides, I've seen others have drinks thrown over them and I've seen several failed attempts to throw things at myself and other cyclists. As for kids hanging out of cars and screaming abuse, no shortage there.
So I make that one serious incident, it did shake me up and I cycled home that night with a fair amount of trepidation. But the incident was partly due to my inexperience, I knew there was no room for a lorry to go by and, foolishly, assumed that the lorry driver would also recognise this. The same situation now would see me in a more primary position due to a lack of trust on my part.
