I don't think I would ever bother to talk to a car driver about an incident like this. Trying to stop driver stupidity one driver at a time is like bailing out the ocean with a thimble. I don't argue with the wind if it tries to blow me over, and I think of stupid car drivers in pretty much the same way. I do blow my horn at them at the time but I treat them like dogs - OK to yell at them during the incident but by the time 30 seconds have passed, they've either forgotten about it or self-justified and will just be angry if confronted. If it's really dangerous and I got a plate number I might report it, but that's never happened to me.

Here are the last couple of dumb ones. The first one I would have reported if I had a plate number. The second one, just an idiot being an idiot.
