Something that happens fairly regularly to me and (I imagine) other cyclists is the overtake followed by braking, indicating (usually in that order) and turning left not far in front of me.
Similarly, artics and trucks with trailers that pull in after an overtake just a few seconds too soon for comfort.
I'm not talking about mad, psychopathic lunges to take me out... just things that make you slow down or veer.
It seems to me that it's always happened and always will.
I'm not in the helmet-cam brigade and shudder to think of people filming some of my more casual moments behind the wheel.
I take a fairly fatalistic view of these things.
As to who'd be to blame, I'd be inclined to cross that bridge only if and when you get to it.
My empirical and in-depth studies of road accidents (work in progress) suggest at this early stage that the best option might be to remain on two wheels and not bump into anything.
If you can manage that, blame will never become an issue.
If you really can manage that, you might then want to consider lasting, peaceful solutions for the Middle East, Korea and Kashmir.
