You guys should go to Europe some time, you'd love it. Ever heard of speed cameras? They book you regardless of being boxed in, what car you drive, what colour your car is, how old you are, if there's someone up your rear end, if you are going with the flow of traffic, if you're overtaking everyone and being a pain....
With a speed camera, if you're going faster than the limit, it books you. Simple as that.
(Note - Speed cameras are hated. People paint the lenses, hit them with pickaxes, and put tires around them and burn them.)
