I agree it really shouldn't but it is, its a fact with two wheeled transport, motorised or otherwise. Like most people, if I were to report every near miss or close pass or cars pulling out on me then I would spend more time reporting them than I would riding!
That said I have had a few truly shocking experience's which I have reported to the Police and despite the lack of any camera footage they have followed my complaint and spoken to the drivers.
The classic close pass was a tractor and trailer, in this case the trailer was a huge muck spreading trailer with the trailer wheels being the same size as the rear wheels on the tractor. As he went past me he pulled into soon and the nearside trailer wheel rubbed on my right shoulder putting a number of circular marks on the arm/shoulder of my Assos jacket.
We chased the tractor and found out which farm it belonged to and I reported it to the Police. Initially the response from the Police was very negative, saying no one has been injured and there are no witnesses, so tough in other words. Then I returned the next day with my jacket and said, how much more evidence do you want? Fair play, they acted pretty quick, located the driver and issued him with a caution.
