Use of radar detectors is prohibited in The Netherlands. I drive right around the speed limit, and on long trips a bit slower - this saves a lot of precious gasoline and costs little in the way of extra time (again, even on long trips) and also makes for more relaxed driving. So my speeding tickets run around $50 a year, typically for driving 54 km in some 50 km zone ...
I'll add a 'blonde joke' here: when use of radar detectors was not prohibited yet, I had a detector in my then (1993)-daily car, an Audi. And I had a (very) blonde girlfriend at the time who once asked how it was that the detector knew about the police car up ahead. I told her jokingly that there was a tiny camera inside the detector, that could recognize the police car from its paint and markings - she believed me. This is the same girl that would wind up her quartz watch every morning. I guess these jokes do have at least some basis in reality?
