When something happens where what I did obviously offends another driver, and they do something to show their unhappiness with me, rather than "giving the finger" I used to smile broadly and wave, as if to say "hi, thanks". I knew that this would really piss off the other driver, seeming to show that I totally misunderstood what he was communicating to me. But I no longer do this, because I have no desire to escalate a road rage situation into actual violence. I always ride or drive with a loaded firearm on my person, but even if I am justified in ever using that gun, it will be a nightmare for me. So I try not to let myself react in any way that would make things worse. I try to just ignore the situation and go on my way.
