Hugh Pickens writes writes: "Sahas Katta writes in Skattertech that a traffic cop pulled him over while driving home and gave him a speeding ticket but thanks to his Android, he ended up walking out of traffic court without having to pay a fine or adding a single point to his record. "I fortunately happened to have Google Tracks running when an officer cited me for speeding while heading back home from a friend’s place," writes Katta. "The speed limit in the area was a mere 25 miles per hour and the cop’s radar gun shockingly clocked me driving over 40 miles per hour." Once in court Katta asked the officer the last time he attended radar gun training, when the device was last calibrated, or the unit’s model number — none of which the officer could answer. "I then presented my time stamped GPS data with details about my average moving speed and maximum speed during my short drive home. Both numbers were well within the posted speed limits," says Katta. "The judge took a moment and declared that I was not guilty, but he had an unusual statement that followed. To avoid any misinterpretations about his ruling, he chose to clarify his decision by citing the lack of evidence on the officer’s part. He mentioned that he was not familiar enough with GPS technology to make a decision based on my evidence, but I can’t help but imagine that it was an important factor.""
