What an idiot. As has already been said, sounds like some holier-than-thou whinger out to cause a fuss over a dented ego.
Now, sometimes people can drive dangerously and cause you not to overtake. I remember once in my 1.1 carb Fiesta (slow car) coming off a roundabout down a dual carriageway accelerating hard as I could, moving out to accelerate some car or other driven by some dude or other. He put his foot down and accelerated from his 50mph to "quite fast", never letting me get any further than drawing alongside. "Oh well I think, he's going faster than I want to be going anyway", so I drop back and pull behind him. Then he slowed gradually down to 40 or 50. I move out to overtake again. He accelerates right up to about 0.9 leptons, and once again I'm unable to get past. So I drop back. And he slows to 40 (This is a dual carriageway btw). I pull out, he speeds up. I drop back. After 3 attempts, I just got wound up, went off at a junction, round the roundabout, and back down onto the DC, letting him carry on. Didn't see him after that, but what a fool!
