that's a slippery slope.. if that becomes court admissible infallible evidence they would subpoena him for the rest of his gps logs and give him a citation for every time in the past he violated the speed limit because they would have proof that he was speeding

also there are tons of calibration and other issues associated with that defense.. the same arguments that apply to get out of speeding tickets could be used to argue why that is inadmissible as proof

bet you it was something like the gps lost signal and interpolated speed based on distance covered over the time the signal was lost.. if the the kid was stopped already that would lower his average speed
