I just hope it is accurate as they claim it to be. A good point is made that no calibration has ever been conducted on the box recorder. Can the box fall out of calibration? When other "detectors" are used in court, calibration of the unit is required, from time to time.
I know too I have seen my GPS speed go nuts, once claiming that my highest speed in my Pinzgauer was over 120mph. Anyone who knows about the Pinz knows it red lines at about 70mph, because of the gearing.
