It's happened to me. I think sometimes they see you do something like that, but they see it's not some knucklehead kid messing around, and they see you didn't get all crazy, and they let it slide.

Maybe he was on his way home and didn't want to stop.

Maybe he was on his way to something he didn't want to be late for.

Or maybe he ran your plates, didn't see any violations and figured he'd let you slide.

You never know.

I find that the older I get, and the nicer car I drive, the more slack I get - as long as I'm not being completely wreckless.
