But wouldn't you agree that it narrows considerably a short distance in front?
It looks like it. How narrow it is is hard to tell. Again, without seeing the actual road it's hard to tell. In fact sometimes it can be deceptive even when you do see it!
The road I live on has traffic islands all along the middle of it, maybe about ten of them on a mile-long stretch. The road is dead straight and they were put there to cut down on dangerous overtaking.
If you look at these islands there doesn't look like there is enough room for a large vehicle to pass a bicycle next to one. One day a huge tipper lorry from the quarry passed me at one of these islands! To this day I have no idea how it managed that without hitting me, it simply does not look like there is the room.
Meanwhile, back at the ranch:
I don't agree that the driver 'moved over'. He is following the centre line and hatched area markings on a perfectly reasonable course through the pinch point. I think it is more meaningful to ask whether the cyclist's line was reasonable. Just from the stills It doesn't look it to me, and the quote from the police report seems to back that up. And remember that this police officer has seen the video, which we have not:
"As the {vehicle} was passing, the cyclist is clearly seen to move further to his offside. There was no apparent reason for this deviation…"
I'd love to be more aggrieved about another poor cyclist being badly treated, I know how crap it is out there in the traffic, but there are just too many ifs and buts on this one.
