Something similar happened to me last year. No parked cars, just a narrow winding unlit country road with very few passing places. I could see a passing place on the opposite side of the road just a few yards behind the approaching vehicle. We both stopped and the other driver started making hand gestures indicating that I should back up. It was at least a quarter of a mile back to a passing place on my side. There was no way I was going to reverse along that road in fading light, too many bends and dangerous for any vehicle behind me. I leaned out the window and called "No, would you back up please". He just sat there revving his engine. I rolled up my windows, locked the doors, turned my engine off and sat there with my arms folded. He got out angrily and started hammering on my window. I pointed out to him that there was a passing place just behind him and it would save us both a lot of time if he reversed into it. He shouted a lot of abuse about elderly women drivers while tugging on my door handle, so I took out a pen and paper and scribbled down his registration number. He watched me and then stomped back to his car and reversed at speed into the space - and smashed his nearside rear light on the bank! I drove past quickly and left him there. I was a bit worried he might turn and follow me but he didn't. My DH told me off for getting into a potentially dangerous situation on a lonely road, but agreed that the other driver should have reversed.
Regardless of what the Highway Code might say I do think common sense and courtesy should prevail sometimes. I just hope I don't meet him on that road again.
