File this one in the "common sense prevails" bin. After Arizona officials installed speed cameras on several sections of the state's highways, motorists revolted. Some challenged the tickets, others didn't even show up at all to contest them. One man resorted to wearing a monkey mask while he sped by the cameras so he could argue that the court couldn't establish it was him.

Normally, politicians might just smugly look past all these antics, but in this case there's a more important reason why they're second guessing their decision. Turns out the speed cameras aren't bringing in enough money. Initial estimates said they might generate as much as $90M, but the actual haul has been closer to $19M. Nothing like a demand of funds to make politicians lose interest.
