And VASCAR is the big problem in Scotland as well - they rarely move the fixed speed cameras and in general they use very brightly marked cars at the side of the road to get you, so the trickiest ones to spot are the dark blue Volvos or Mondeos running with video/VASCAR.
Although the A9 to Thurso and back this weekend was fun even without radar/laser detectors. As mentioned above, just travel a reasonable amount faster than the speed limit and everything which catches you is a policeman or someone you can let fly past you in turn.
