Zombie, glad to hear you survived a brush with the Reaper. Whenever I have someone tailgating me, much like you did, I often squeeze the brakes multiple times followed by dropping my left arm and hand to my side and waving the car back. If they don't get it, the first chance I get at a light or stop sign I turn, open my helmet and tell them to back off. Unfortunately there are too may A-holes on the road. Last March I was rear-ended at a toll booth by a Ford Explorer. Surprisingly there was little damage and the guys insurance paid for the repairs.
