with respect to the earlier post about the bloke blocking a box junction, a very long time ago i rode down Farringdon Road from Mount Pleasant to the box junction with Clerkenwell Road, the lights changed, someone shot the light and got stranded as all the other lanes moved up to him at the same time, leaving the junction utterly jammed with a long line of traffic up against him from all four sides.
In that moment a pedestrian seemed to appear from the ground, in incandescent rage, waving his hands above his head by the driver's window and howling 'you've done it now, you've done it now, look what you've done you idiot, what are you going to do now? etc etc' to the immense amusement of everyone present while the erring driver tried to squirm so low into their seat that they could disappear.
