Although about 700,000 tickets have been issued since Arizona's 76-camera plan was rolled out last year, a mere $37 million of the $127 million in fines and surcharges has been collected. That is because Arizonans have realised that they can simply ignore tickets sent to them in the post, and the authorities cannot prove that they have received them. Unless the tickets are served in person something Arizona cannot afford to do they become void after three months.
