...their incompetence robs them of the ability to realize it…

Now that’s just convoluted, but it does make then another victimized class.

But I like this:

He’s just a moron. (attribution error) – Is the driver that cut you off a jerk? Or is he a good guy who didn’t see you because he’s distracted by something else going on in his life. Judging by the finger that you chose to hold up, you think he’s a jerk. That’s about par for the course, as most people tend to over-emphasize personality-based explanations for the actions of others.

I don’t think they’re morons; but I do attribute it to the notion that they’re “libertarian drivers” and if they had a choice between sending the rest of us into the cornfield in order to get home five minutes sooner, they would…weaving through traffic because their time is more important than my time.

I get a real kick when they ding someone during their speedweave through congestion exercise and save the finger for the greeting as I pass them by.
