• I think the roundabout is the one at RH6 9BW. I remembered the side road coming in at a right angle, but that seems to be a false memory.

  • That's a full roundabout, though, not a mini-roundabout. None of what I wrote above applies here. Not the best design I've ever seen, but not the worst by any means. Are you sure it was that one? The driver coming in from the right would most certainly not have been able to see you here until quite late.

  • I'll have another look tomorrow. It's a longish road.

  • I looked at the street view and it was this roundabout. I've attached a diagram showing our relative positions as I entered. As I said, I saw him a bit before the first position shown. Should I have waited, do you think, given where we were? My judgement about how safe it was to enter the junction was partly driven by the fact that there were two entry lanes on my side and clearly passing room on the roundabout itself. His judgement as to the danger of the manoeuvre was probably driven by the fact he had to pass me back into one lane of traffic at his exit.
