One of my favorite parts of that show would be when Rockford would get fed up with somebody who was following him in his car. He would skid around in a u-turn blocking the guy - get out, walk over and yank the guy out of his car.
We used to call the sliding K-turn he used to do a “Rockford” as in pulling a Rockford. I perfected it in my youth and can still do it pretty well today. It makes my adult kids scream at me when I do it.
