This is Absurd

Police Stop Car Due to Air Freshner

I can't say it enough...any violation of the law is enough to get you pulled over.  In Virginia, your air fresheners must conform to a certain size.  The police saw an oversized air freshener hanging from a defendant's mirror and pulled him over.  Of course he had drugs in the car, but that is besides the point.
