Aren't you warned in the US well before the camera's location? In Sydney lots of people complain about the speed cameras but except for the mobile cameras, there are huge honking signs telling you there is a camera ahead. Most people will start to slow down well before the camera. On our highways we also have average speed cameras, 2 cameras will take a shot and if your average was too high, you get fined. But these are also well signed. Yet people still get caught all the time. I'd have more sympathy for the people getting caught except that they are literally given a cheat sheet on the road for when to slow down and not get caught.
