I know this does not answer your question, but the following happened to me. I was stopped at a junction, wishing to turn right, there was a car parked on the road I wished to join, on my left, with its rear end at the start of where the pavement started to curve round. Thus it was effectively blocking my view to the left. I had to nose right out to see past this car.
While I was doing this there was a car waiting to turn right into the road I was leaving, the occupants of which where stopped in the middle of the road, staring at me, when they eventually turned in, the car stopped opposite me. It turned out the driver was an off-duty policeman in his own car, he informed me that what I was doing ( pulling out over the give way line and stopping) was dangerous driving, even though my view was obviously restricted.
Everyone else I asked said they would have done the same, was I in the wrong?
