Years ago, I was getting off the highway turning left. An idiot in a Porsche convertible passed me on the right, driving like he was out of smokes, then stops on a dime at the next red light. I had to get on my brakes and downshift like crazy so my big rig wouldn't squash his mid life crisis vehicle like a bug. As he's holding his phone to his head, he sees how close I am to his rear bumper, turns in his seat and flips me off.

Well, I set the parking brakes, jumped down to the ground, grabbed my "tire thumper", and proceeded towards his car to.....explain things to him.

He must've remembered an appointment he was late for. He burned rubber through the red light and was gone before I could introduce myself.
