Keeping a GPS-tracking app running on your phone while driving might just provide the hard evidence to fight an illegitimate traffic ticket. At least that's how one Android-wielding driver successfully nixed an erroneous speeding ticket.
Sahas Katta writes about his fascination with Google's My Tracks app — normally a fitness-minded app, but which records lots of movement data for any situation, including a top speed. Pulled over and cited, Katta knew he'd been flagged far beyond his top speed, but found the evidence on his phone.
In court, Katta calmly asked after the training and calibration of the radar gun, then presented his time-stamped GPS data and explained the My Tracks app to the judge. The judge ultimately said it was the officer's lack of evidence that led to Katta's dismissed ticket, but as Katta points out, he wouldn't have had the footing to make that argument, or the supplementary evidence, without his GPS app. Suddenly, the price of a phone-mounting car dock seems more like an investment.
