[Delphinus]

Midget, I agree if someone were to sit that close to you that it's a bit over the top but I wasn't doing that.

I would still argue that it's more the reaction and less the initial transgression that qualifies as dickish or undickish. It's a fact of life that there are bright lights out there. I find myself being blinded all the time too, and I sit higher than your lowrider. I just use my night mode mirror when it's behind me, and I try not to stare at the headlights when it's oncoming. Unless I'm 100% certain it's highbeams (and if I'm in doubt, I'll extend the benefit of the doubt), I won't click my highbeams at someone. Besides, there's also a trick you can use, if the foglamps are on then it's not highbeams. Unless the foglamps are installed incorrectly you're not supposed to be able to have both on. So foglamps and bright lights == just bright lights. Brightlights and foglamps off == maybe its highbeams.

But let's face it getting angry over headlights is a bit... petty, no? Do we really have nothing else we can direct our aggression towards in our life?

See, here's my take. Here's a choice: Flip your mirror into night mode, or chase the person for the better part of half an hour trying to get the point across that you want to kill him? Let the punishment fit the crime. Bright headlights? If it's THAT upsetting then I'd say there is a different problem at play. Sorry, I stand by the assertion that people become jerks once behind the wheel. For all I know this person could be the nicest person you'd ever meet in person but that reaction was so far over the line, there's no conscionable defense of it.
