Sobering reading - I am a lot more relaxed to other people driving like tools than I used to be (partly due to more experience of the nutjobs that seem to drive in city centres) but stuff like that is just mental. Hell, AFAIK the area it happened in isn't even a scuzzpit.
Huge sympathy for the poor guy, utterly baffles what goes through the thought process of someone would do this over a place in line.
Maybe time to think more about whether or not it's really worth getting worked up over that potential nutjob that _really_ wants to slow down your day by 5 seconds.
Awaits barrage of internet bravado about what people would do if they were in a similar situation.
