Generally speaking, I am not in favour of lashing out. I used to be prone to it, but I got older.
The only thing I've done recently was almost suicidally stupid, but it had the desired effect. Quite why I did it, in my late forties. I have no idea.
I was commuting up a hill on some NSL single-carriageway I drive and ride on frequently. It has doble unbroken lines between lanes and I was in what might be called a prominent secondary, alone in my lane.
A line of cars coming towards me, but no-one in my direction. Out of the line of cars pops an overtaker, across the doulbe line and headed at speed my way. He'd have missed me, but not by much.
I was furious (still not sure quite why) so I swung right out into my lane and forced him to swerve back into his lane and miss me by not very much. Altogether, it was a cluster-fornication. Two or three cars honked at me or him. He honked at me (with his foot on the sustain pedal, by the sound of it). Two or three cars stooped heavily at the nose as they braked.
I'm not particularly proud of having done it and it doesn't fit with my usual manners on the road.
I imagine he learned a valuable lesson, but I might easily have caused a fairly ghastly pile-up.
Confession cleanses the soul. Apparently.
