Trailer hitch testicles are IMHO are tasteless and without any redeeming factors. They aren’t funny. With that said, I don’t see how they could be any more distracting than bumper stickers, and banning bumper stickers isn’t a slippery slope I want to go on.
I've never gotten a ticket for anything. OTOH I have a brother who likes to shout to the world from his bumpers. He's forever 'splainin his self to the man.
