Just had this thought whilst driving home late last night, passing one of those ford territorys parked on mt ouselly checking speeds in the northbound direction. Does someone have to be sitting in there sipping coffe all night? Or do they just get parked and checked up on every so often? Reminds me of a story I once heard about some cheeky buggers who stole the plates off one of those cars and proceeded to speed back and forth infront of the camera with said plates attached. No idea if it was true or not.
