Maybe I'm stupid, maybe I'm a little naive - but what the heck is a speedcam? Is it just what it sounds like? If you're speeding, your picture is taken and you get a ticket in the mail?
Is this a UK thing? I work in Los Angeles, and I always thought that if there was something wacky with anything related to traffic, I would encounter it in my commute - but I have never seen one of these things...
