When people ride my ass I just work the throttle a bit and they're covered in black smoke (guys that dump smoke all over anything and everything just cause they can are douches, but there are times that its justified). Then when I need to pass somebody and can't change lanes or we're in the left lane... between the "holy fawking shit!" factor of the big steel bumper and bull horns on the grill coming up on their ass and the fact that my headlights are right about eye level for most cars/SUVs, people just tend to get outta my way.

Past that, I don't engage in "traffic wars" or road rage or anything. Somebody cuts me off, I'll cuss at em a bit but no fingers, fists, horns, lights, anything. I'm always armed, and in making the choice to carry a firearm we (I assume most of us here carry) have the responsibility to avoid conflicts whenever possible. Potentially starting one by (rightfully) expressing your anger at some asshat on the road is irresponsible. Now if by chance I leave all my guns at home and don't have any on me or in the vehicle, I tend to drive like a dick, but that's a rare occasion.
