Prior to radar detectors many years ago I would get the infrequent speeding ticket. Back in the eighties, I had a toy running mid tens at about 128. Even became a super pro track champion of a Virginia track in '86. Recently on a dyno day a fellow that had put his nice Mustang on the treadmill prior to mine and seemed to be upset that I was about 130 HP over him walked up to me saying "I can still beat you out there on the street". I agreed with him completely. Sure, I might blast it into triple digits in a remote location to test a brake fluid flush or a new set of pads, but for regular driving, never see the need. The "privilege to drive; it is no right" stays in tact and never increases in cost. I find the track times get the need for speed on the street out of the system, the quarter/eighth mile, mile, or road course work equally as well.
That being said, I was pulled over for no front tag thanked by the officers for now having the chance to see a Ford GT up close.
Cost of radar detector, installation time, panic on alarm, speeding tickets, attorny fee, court costs, . . . I just choose not to pay; and still enjoy the car the way it was meant to be driven.
