Hah. We're now implementing speed cameras in the US. They take a picture of your car if it hits over 11mph (gee, not too arbitrary) and you get your ticket in the mail. It's a complete joke of a revenue generator since it's basically a tax that treats a doctor who makes 6k a month the same as a lawnmower you makes 1k.

And let's not even get started on the insane crap they've tried to pull on us in Virginia over the last few years...
