overtake going about the same speed as another in the inside lane, forcing everyone behind them to wait.

The pointlessly angry ones are the worst though, I get feeling frustrated being stuck behind a single car doing 30 on a 60 limit single carriageway but not getting right up somebody's arse in a blind rage, horn blaring and headlights flashing when there's no possible way of them going any faster. I had a truck doing this to me not so long ago, thought initially they were trying to be helpful - maybe my boot had opened or I had a flat tyre? Nope, just sheer pointless, mindless anger. It was like the film Duel. I gave the traditional middle fingered salute out the window (which could have turned out to be an unwise move to someone in charge of a HGV but thankfully he then backed off). Same thing happened to me - except this time a car - less than a week later. On a dark, wet, windy road with a sheer drop down the side. Again, absolutely nothing I could have done to increase my speed without moving to the wrong side of the road and overtaking several vehicles on blind bends. These people are fucking mental.
