I had a c*** in a dumper truck fail to overtake me the other morning. Not that that stopped him. Approaching red light in good secondary leading onto a roundabout, hear the engine revving, he moves out into the second lane but then starts to move back into the inside lane again before he's passed me. I smacked the side of his truck with my palm three times (that's how close he was) then I braked as he kept coming. Then he got very aggressive, swinging RIGHT and then back left, ending up stopped diagonally, blocking both lanes. As the light was still red I hopped on the verge, got in front of him and gave him a questioning shrug as to why he nearly killed me. I couldn't hear his response through the closed window, but it seemed to consists of the same two words repeated over and over, punctuated occasionally by a word beginning with 'W'. Sadly in the heat of the moment I neglected to take his reg and contact his employers. Next time I will. Since then I've taken primary leading to this junctiong, though I doubt it would have done much to prevent such a t*** attempting this again. Rant over.
