Well anyone who's looked at the literature should know that radar detectors are useful and do not allow drivers to speed with impunity as alleged by the idiots for public road safety...
studies show they aren't as bad as some people think.
But yes, be prepared to say goodbye to them. Police I talk to say they don't work effectively enough for them to care about it, so it's a push by zealots who probably 'think' they are amazing super devices that suddently enable you to drive 200km/h everywhere without getting caught. Myself having never had a speeding ticket after 15 years of driving, 2 years of which with a radar detector, I can say that they are useful for a lot of things, and avoiding speeding cameras is the least of their uses.
