That road looked treacherous and there were a number of times when I thought I'd reached the point where the accident was going to happen. I also thought the cyclist was going too fast for the traffic conditions, especially on the approach to the accident scene.
The car emerging from the left had its front end sticking into the cyclist's path and there was the another approaching head on ready to turn right across him.
For some reason vehicle drivers seem to become consumed the politeness in these situations, almost to the point of benevolent incontinence. They start waving at each other and assume authority to beckon the other car out into the path of oncoming traffic. Unbelievably, the driver receiving the waving or manic flashing of headlights places complete trust in this totally unknown person's judgement and they carry out the manoeuvre in blind faith. I've noticed that in these situations, drivers tend to focus more on the waving or headlight flashing than what is actually happening around them. It's a growing trend, along with updating social media status whilst driving.
