I am a gringo that lived in Australia for 6 years. In the state where I lived the police had two kinds of cameras.
Large fixed cameras were well marked a couple of kilometers ahead. You are only at risk for a short time, But you would be amazed how the Aussies drove right smack on the speed limit as soon as they saw the signs. Speeding under the camera netted you big points, double on holidays.
The other kind were unmanned mobile units in white vans. Typically placed in urban areas in plain sight (at the bottom of a hill--bastards!). A fine, but no points however.
Another Aussie state actually had a law that the cops could not hide while operating a radar gun.
I found the Aussies to be extremely aggressive drivers, but only at slow speeds and in parking lots. The only time I saw Mad Max, he was driving with 'P' plates or at Summer Nats.
Bottom line: visible enforcement is strong prevention. Most U.S. departments are really after the revenue.
It more than undermines it, it encourages speeding in areas that don't show radar. Turn on an inverse of the map and it gives you speeding zones rather than radar zones.
The marketing attempt at "... RadarLoc encourages law-abiding behavior." is patently false. It encourages the opposite, speeding outside radar enforced zones.
