I think it probably falls under “distracted driving” - not that there’s anything wrong with that.
It was really just a joke about a line I heard once in a movie. I thought the term was notable.
The point of all this is that this deputy’s follow-up reason (then purported to be the primary reason as the ‘verbal beatdown’ continued), was all BS. They saw nothing, could not, nor ever prove anything regarding it.
The two Rambos didn’t like getting flipped off and they used their status to oppress the driver. Simple and plain.
