That guy was quite the opposite of a pickup-driving doof I encountered recently. Evidently I failed to accelerate away from a red light quickly enough for his tastes and the litany I heard through my open moonroof about it would have made a sailor blush. So I saluted him and then he offered to pull over and fight. Feeling that even the salute was more effort than should have been wasted on him, I proceeded to my destination. I saw that he followed, but then the strangest thing happened: I got out of my car, and he left. Too bad. Could have been educational for him.
