Once on I-40 near Hickory, I was in the right lane doing my usual 13-14 over and an unmarked was slowly easing by on my left. I saw the car close on him, get right on his azz and flash his lights. The unmarked continued to ease on past me, moved over to the right lane in front of me and the impatient "flasher" went past. Then the popo eased back over into the left lane behind him and that was when both of us realized it was da man ... as he hit the "oh schit" lights ....
I giggled like a school girl
