California has an obscure law that says something like if 90% of the people are breaking a law (going over a speed) the state needs to up, or lower, the speed limit. A lawyer got the county to up the speed limit on a boulevard I drive, after he got mad over a ticket. (I don't know the details. It's something to do with Speed Traps I think? I remember seeing an angry Lawyer, and felt he had a right to be pissed in a local newspaper.)
