However you feel about photo radar speed enforcement, it's a big money-maker for cities.
Scottsdale made more than a million dollars in revenue last year alone.
So, they'll likely be around for a while.
But what if you think the ticket is unfair or incorrect?
Some people are fighting back in court and winning...or they're learning the rules and avoiding paying the ticket altogether.
By law, cities must personally serve the citation to you.
After they file in court, they have 90 days to make at least three attempts to do that.
If the process server is unsuccessful, the driver may get off without having to pay the ticket.
But it's not always easy.
If cities go further and get an alternative service, they are able to tape the citation to your door, send you a certified letter and call that you are being served.
Ryan Cummings with R and R Law Group says if you acknowledge the process server by answering questions through the door or even communicating through the window, a judge might consider that as you being served.
And he says, if you acknowledge the ticket by calling the courts for information, you may waive service altogether.
We see complaints from parents who get tickets even though their child was driving.
Cummings says you can fight those tickets.
Unlike parking tickets which go to the car, photo radar tickets go to the driver.
