Years ago I doing about 15 over in the right hand lane, another car slowly creeping past me in the left lane...maybe 1 mph faster with another car right on his azz (Nascar drafting...). Car to my left gets past me, moves into my lane to let the "Nascar driver" by....then immediately moved back over to the left lane, right behind the "drafter"....
And lit his azz up
This was before unmarked cars were common....I smiled for miles and miles.
