I've had something not dissimilar once. Was driving, no hurry, so stopped to let a queue of cars coming in the opposite direction through as they passed a number of cars parked on their side of the road. I had priority, but not being in a hurry and feeling chilled was happy to let them go.
Anyway, the first car through stopped and parked adjacent to me, thus blocking the passage of the following cars. The old boy in the second car was effing and jeffing, giving me the bird, really going for it. Then he finally clocked me sat their in my muscle vest on my way home from the Gym, half his age, three times his size, then there was a car crash of expressions on his face as he realised he'd dropped a serious clanger. His mouth had been writing cheques that his body had no hope of cashing if it went sideways on him.
Within a few seconds the car that had parked realised their error and rolled forward a few car lengths, no harm done, but the driver of car two was definitely living on borrowed time if that's his behaviour. I'm not interested in road rage, I just let them get on with it, but the old feller would do well to remember that people often die through such incidents (the Dad of one of my Daughters friends died during one).
How can something so meaningless be worth risking life and limb over?
