The company I work for installed nanny cams in all the company vehicles. If you go more than 10mph over the speed limit, the stupid mother-in-law on the windshield starts bitching “Please slow down”. Someone cuts you off, and the stupid mother-in-law bitches “Maintain safe distance”. If you rub your nose, eye, ear, check your mirrors, etc, the stupid mother-in-law bitches “Distracted driving”.🙄
In my car it’s the stupid son-in-law .
