Flash Your Headlights?

Back in the day before radar detectors, the free market came up with a very inventive way to warn fellow travelers and commuters about law enforcement doling out speeding tickets. Drivers used to flash their low beams (during the day) or high beams (at night) to alert oncoming drivers that there was (municipal cops, sheriff, county constable, highway patrol, school district cops, FBI, private security, Mounties, military police, agents from the Matrix, the TSA, Homeland Security, the International Federation of Planets, and anybody else with a badge, and a gun, and a radar detector) waiting ahead to pull you over and give you a speeding ticket.
Is there any worse bummer than getting pulled over? I'm talking relatively speaking. Not like, 'Sonofabitch I got pulled over today. It was the worst thing that could have happened.' 'Oh really. I just found out that I have cancer.' Just in a pissed off, this is going to be a hassle, man I was only going as fast as everybody else, why don't you pull over the old guy in the left lane going 37 on I-45 bummer.
You're looking at a minimum of a couple of hundy in fines plus you have to figure out some way to make sure your insurance company doesn't find out because they'll either jack up your rates or cancel your ass altogether. Insurance is like sorry employees. They love you as long as you're paying just don't ask them to do anything.
