Nabbed for speeding? GPS data could get you off the hook

arstechnica.com — An 18-year-old in Colorado was found not guilty of going 17 miles over the speed limit thanks to the data logged on the GPS device installed in his car. GPS may now be able to get you out of speeding tickets, but it could also act as a double-edged sword.

Keep in mind, this was not a gps navigation device used to find an address. This was a <a href="http://www.rmtracking.com">gps tracking</a> device.

There are several human error factors with radar:
1) Clocking the wrong vehicle when there is more than one vehicle or in a passing situation.
2) Stationary or Mobile radar. Stationary is much more accurate because the radar is not having to calculate the police car speed.
3) Catching and identifying the right vehicle that was speeding. This can be especially difficult while running stationary radar because of the delay of pulling out into traffic to chase after the suspect vehicle.
4) Radar calibration, which should occur at least once per year. This should not be confused with an officer checking calibration with tuning forks. The calibration should be checked before and after each ticket is issued, but at a minimum, at the beginning and end of the officer's shift.
5) Hills and turns in the road can easily affect radar readings. Radar should not be run around hills and turns. I have seen radar indicate (for a few seconds) speeds of several hundred miles per hour when it was obvious the vehicle was only traveling at a speed of maybe 50 - 75 MPH.
6) A/C or heater fan can interfere with radar readings.
