No one drives the fucking speed limit on the freeways. This is nothing more than a way for them to generate income.
Years ago at the Phoenix Forum I got nailed outside the hotel. Fuckers.
However, at the time these were run by a private company and not hooked up to the city. In other words, this private company would generate the ticket, send it to you, and local law enforcement didn't know about it until after you sent them a check. In this case, I never paid it and never heard a peep about it.
