Vehicle speedo's are normally calibrated toa higher level, thus making you think you're going faster than you really are. Formula one race teams use GPS to calibrate speedometers... go figure!
Of course, there's no telling what level the police calibrate their Gatso's to, so best to not risk using yer GPS in court!
It's a tradition, or an old charter or something...
I was more concerned about creating evidence that could be used against me in court
I'm not sure about the speedo being calibrated low, I find the same error on the bike, or in a range of cars. There are some vascar markers hear abouts and one day I'll go out with a stop watch and run a proper test.
All the best.
