Not really rage, but annoyed. I have some payback methods like the one I use for tailgaters: Tap my brakes and slow down. I have flipped off a few drivers.
I've never actually been enraged - highly irritated at best and these days, I don't even raise my middle finger because you never know what the other person is going to do. I rarely drive with my windows open, so I will yell inside the car. What I have done is lower my window for someone crossing the street against the light because they're so engrossed in their iPhones and have their earplugs in that they don't even see me.
