You do realize radar detector technology has come along way from the days of the FuzzBuster?I used one years ago. Don't remember the brand. But here in Oregon, they are banned. But not always ticketed for having them. The biggest issue is there is dummy signals put up all over the place so your detector is always going off and you never really know if its the law or not. And the traffic cameras now will hit you if you are three miles over the limit. And those are at damn near every intersection.
Last ticket I got, I over paid the ticket. When they sent me a check for the overage, I tossed it. That kept the file open, so it never showed up on my driving record. 8 years later, the state put the $5 in the wildlife fund. So it still never really showed up because the violation drops after 7 years.
My radar detector has a built in GPS that will automatically block false sources of radiation if driven by the same location three times. It also filters out the passive radar signals from highway traffic monitoring systems, and does a really good job of filtering out radiation transmissions from all of the car safety systems such as Blind Spot Monitoring, Adaptive Cruise Control, etc. Since the locations of fixed radar guns and red light cameras are known, the detector warns me of said device as I approach it.
What I'm really trying to say is that when my radar detector goes off there is most likely a cop in the area.
I've tried Waze and found it was out of date at least a third of the time. Cops are nowhere to be seen, or worse, sitting right there in the median with no corresponding alert. For me, Waze is next to useless.
