1. Driving along at normal speed along a two-lane highway with your 90-year-old mother-in-law bundled up in the passenger seat on the way home to Hamburg in the late afternoon when you see a small car pulling out to pass a semi-trailer coming against you and think well since I’ve got the lights on he’ll see me and pull back in behind the truck but then you realise the jerk is actually going to try to pass the semi-trailer with his gutless wonder and just when you think the two of you are going to smash into each other head-on any second you hit the binders and veer off to roll through the rough grass shoulder leaning on the horn and screaming FUCK! WHAT AN IDIOT! as he’s still only half-way past the semi which has also pulled over as far as he can without landing in the ditch and you’re wishing you’d had the presence of mind to get the guy’s license number but of course all you can think of at a time like that is trying to stay on the road to make sure the both of you don’t get killed.
2. The body’s reaction to the mind’s desire to choke the living shit out of some driver who really deserves it.
