I was running my Passport 8500 -- probably 8 years old -- in Highway mode yesterday, and it never made a peep as I approached a SCHP trooper. He asked me if my detector picked his radar up, and I asked him if he was running one.
He said he has a pretty new, hi-tech unit that has a "mute" button until he sees a suspicious vehicle (me) then he can take a reading. He said he normally never gives a break to anyone running a detector, but that I was honest and didn't try to BS him, so he wrote me up for "only" 9 over, saving me more than $100 and 2 points. Maybe it was my gray hair or handsome face.
I returned the favor by thanking him and giving a short seminar on Secant Error for moving radar units. Actually, I never got off the bike, so could not confirm that he was running his radar, but he gave me a pretty accurate number that my McCruise was set on.
Maybe someone can wire up a screamer or some such detector accessory so that it kills the McCruise just like when the brake-light switch circuit is closed? Nah -- too many false alarms from supermarket doors,
