Your language gives you away here col. Apart from one mention of 'the motorist' and the rest is about the vehicle being wrong and the vehicle making allowances?
Unless its a top end Merc, Bimmer or somesuch, the vehicle does nothing by itself. Its an object. You've dehumanised the human being responsible for the tonne and a half of metal. Instead, you've made the vehicle some sort of irresistable force of nature, a mechanised beast outside of human intervention.
As a nation, we've got used to the idea that the car is the default mode of transport. I could get political, but I'm not going there. Its largely our own fault. This is a convention, not a law of nature or even the law of the land. The cyclist, whether a model road-user or a pavement-hopping RLJer presents a challenge to that convention, and we're increasingly used as the lightening rod for motorists' frustrations in the media and, more importantly, on the roads. In the same way you've dehumanised the driver, we're dehumanised as cyclists. And, as anyone who's read anything about prison camps, the first step in normal people behaving attrociously to their fellow human beings is to learn to view them as non-human. A large minority of our fellow humans who drive a car regard cyclists as another species, which makes it easier to place our lives at risk by their behaviour.
And that's the point - many cyclist behave badly, placing their lives at risk. Many motorists behave badly, placing cyclists' lives at risk. Its a rigged game, and its not rigged in our favour.
(FFS Bollo finish it up!) I consider myself a courteous, careful, law-abiding cyclist who respects other road users and who tries, and sometimes fails, to integrate with the traffic. Where we really fall out Col is that I expect the same back from other road users, irrespective of the means of transport that I've chosen.
