To the Miata driver heading West on I-40 near Durham, NC who flashed their high beams at me in the Black Mustang GT...

...to warn me about the State Trooper posted up a mile down the road, you're a real bro! I wasn't speeding heavily or anything, but prob going just enough over to get a ticket.Who else does this when they spot a speed trap? What other signals do you use? And what vehicles do you typically warn? via /r/cars http://ift.tt/2unk0QE
