I'm glad that you included the radar detector in the list of tips.
I used to drive a silver 1996 Ford Mustang GT - no fancy rims- at 80-90 mph all the time in the 65 and 70 mph zones in NC, SC, GA and AL. Was never noticed and never got a ticket in that car. Probably having cruise control helped. Most of the time, it was set at exactly 80 mph with an occasional spurt to 110 mph. I miss that car.
