I think you're joking ... but this is almost always a bad idea, in case you aren't. Nobody ever wants to admit that they're wrong, including drivers. People occasionally post about confronting bad drivers, and it usually escalates before both people go their separate ways.
Well, I was mostly joking. The thought did occur to me, but only because I have a nasty diplomatic "moral relativity" streak. (I blame Joss Whedon) Also curiosity.
My driving instructor noted this behavior, and cited fear as the reason for it. What happens when you nearly bump into someone at the grocery store? Likely nothing more than an "excuse me". Near-misses when driving usually result in much more passionate responses, likely due to the fact that there is fear involved.
This is a good point. When there is a near miss in a potentially lethal situation, no matter whose fault is was, it sends a rush of potent chemicals rushing though the brain that can't be good for rational diplomacy.
I have often felt like Jane Goodall observing all the chimps in traffic in my blind at the corner cafe.
Yeah, we are definitely out of our evolutionary depth when we try navigating massive steel projectiles around in each others general direction.
