I thought I was going to be beaten up last summer following a similar incident, and yes, I hold my hands up, my behaviour didn't help calm the situation. Narrow road, ditches both sides, no room for two cars to pass one another without the aid of a passing place, of which there were many. A van came up behind me, revving the engine, driving too close etc, so I decided against stopping at the side and getting on the verge to let him past and instead got in the middle of the lane so he couldn't overtake and carried on to the next passing place.
However, when we got there, a car was coming in the opposite direction so I kept going and he had to pull in to let the other car past. He caught up with me shortly before the next passing place and again sat right on my back wheel, being an arse ... only there was yet another car coming in the opposite direction, so I once again I kept going. Believe it or not, this happened again and again at every passing place on this lengthy narrow stretch and by the time the road was wide enough for him to safely pass, he was using his horn and I'd given up looking back over my shoulder to see if he was going to run me over.
When I finally let him overtake, he drove alongside me and his passenger gave me a whole load of abuse out of the window, which is when I began to wonder what would happen next. Yet another car approached from the opposite direction so he zoomed off in a cloud of exhaust smoke. If he'd driven patiently behind me at the very beginning, none of it would have happened, and I kept being stubborn because he kept being an arse, but in retrospect, I should have just let the bleeper past.
