I once worked for the company who supplied petrol injection to Rover and Land Rover. We released a high performance tune for the West Midlands Police traffic vehicles.
I was a test driver and spoke regularly to the WM Police drivers; and one other driver at my company was an ex-copper.
I commute cycled to work, but took the SD1s and Range Rovers to the test track.
Stories I heared from the Police drivers were no surprise, as I also had friends at Solihull Ambulance Station ( who preferred to be addressed as Emergency Paramedic Units rather than ambulance drivers ).
Comments like "Bloody silly place to ride a pushbike" and "You're f*ckin nuts, mate" were said when I told them I rode round Birmingham's Queensway during rushhour and along the major arterial routes in and out of the city.
What the cops AND the Emergency Paramedic Units want is to NOT have to scrape cyclists off the carriageway. Like in the stories about cyclists who were riding "right in the middle of the f*cking lane".
From the policeman's point of view, a cyclist riding two foot from the kerb has LESS chance of being hit than a cyclist riding in the centre of the carriageway. Most motorists are fairly observant, but there are some who look in shop windows or at a short skirt. When this happens, the car will more than likely roll past the cyclist who is cycling two feet away from the kerb, but straight into the back of the cyclist who is in the middle of the car's width.
There are a myriad of situations one could argue about. When I occupy 'primary' I am wary that the driver behind me might not be looking in the right direction, ie forward. There is no accounting for stupidity. This is why I spend most of my cycling miles in a position where a motorist 'probably' won't hit me if he/she fails to see me because their mind was elsewhere.
Saying such things as "This is a position in the middle of a lane and should be considered the cyclists default position. This position will be directly in the line of sight of drivers so ensuring that the rider is visible and able to communicate with drivers behind", go against all that I have grown up to learn as being the MOST dangerous place to ride.
No doubt someone will reply with "You're WRONG". Lets see how long it is before the next incident when someone is shouted at, 'buzzed' or bumped for being in the middle of the carriageway.
