Since we are discussing bad driving. I have a question for California residents. I was driving on a freeway the other day when a guy in a duelly truck started tailgating a car in front really close, maybe 2 or 3 feet. Anyways, this truck then starts flashing blue and red brake lights, similar to police lights but are from the brake lights instead of on top of the truck. The guy being tailgated pulls over on the shoulder thinking he is being stopped, the truck then speeds up and does the same thing to the cars in front of him in the fast lane. He took off a like a bat out of hell once clear.
My question is, have you ever known or seen a non police car flash lights similar to police lights from the brake light area? Was this a legit police action or just some dumbass?
