Hot_Georgia, you may extend your observations into NE Florida. I've never had anywhere near the rage from a car behind me people here seem to fear, and I have changed my driving habits to fit the mold of the most conservative hypermiler.

Instead, my general experience has been the opposite. It's the people behind me who have been afraid to drive confrontationally. Instead of beeping, honking, flagging, shouting, etc., they either pass me calmy or - GASP - settle in to my own speed limit level pace acceptingly.
