As I said and other people have said the camera doesn't pick up everything and their right. The oneway layout prevents any dodgy movements at that junction and the grid lock restricts it further and there was much more space than it appears. My initial estimate of 2-3 minutes was conservative, the traffic is abominable. I had a good 5 minutes before sitting in traffic to assess the situation. I think my tact of letting other vehicles taking the impact rather than me instead of expecting them to see me is a good one. As I said I just found it funny in all that time she never once looked at the HGV driver. That's all well saying you'd wait behind the HGV, in another place I'd wait behind it too but in that situation you'd be waiting all day B).
