RE: Hmmmmm it s based on GPS-my sat nav gives an instantaneous speed read out-more accurate than speedo
I am sure that the court asked that question am fairly sure that the boffins gadget will be very accurate as it will be GPS based and I am sure he had to demonstrate its accuracy to the court. There are many documented cases of inaccurate hairdrier readings. I am amazed they can ever get a conviction with them as many things can cause an inaccurate reading.
