In a car park today, a van reversed into me while I was part way through a manoeuvre. Diagram attached. I was in some bays perpendicular to another set of bays.
I had reversed to do a three point turn around the back of a van. I had just stopped and was about to drive off, when the van just reversed into me and hit my side rear.
I was there first, and he reversed, but as I was in a manoeuvre and in an unexpected place, could he claim I was to blame? AIBU to think I was not to blame.
YABU - I'm not to blame
YANBU - It's a 50:50 accident
(I know life is a bit more non-binary than that, but interested for views).
