I was driving along a road with cars parked along both sides so only a single lane available for traffic. I needed to turn right into a car park, but the entrance was blocked by a car waiting to come out and turn towards me. There was at least one car behind me so I couldn’t back up. Normally I would have gone straight ahead and turned in the road to the left a little ahead, but a van was blocking both sides of the turning as they were trying to pull out and had pulled forward at an angle to see past the parked cars. There was no other turning along the road, so had to drive to the end of the longish wiggly road, turn around the a cul de sac and come back again, at which point I was able to pull in and park. No idea where the car(s) behind me went, but possibly turned into one of the drives a bit further along.
All fine so far? I just shrugged it off, although it was a bit of a nuisance and made me a few minutes later than intended. However one of the other people had seen me unable to turn and was highly indignant on my behalf. It sparked a debate about rights of way (it was a bit live action mumsnet!) and everyone seemed to have a different opinion.
TLDR: Given the situation illustrated below, who had right of way?
