Sean,
 My dad runs a business in Scottsdale, with one delivery truck. The guy that
drives the truck got a photo-radar ticket, but since it was registered in
his name, they sent the ticket to my dad, with a photo of the vehicle. He
called the court (or the police?) explaining that the photo obviously wasn't
him, so they they sent him a form where he could VOLUNTARILY identify the
driver. To make a short story shorter, his driver got out of a ticket. The
police have to be able to prove it was you driving the car, not just that it
was your car that was speeding (ran the light, etc.) At least that's the way
it is in Scottsdale. Fight it!
