Bearing in mind that I know that the speedometer in my own car is specified to overread by about 11%, I do my best to stick to speed limits.
As a result, I have recently experienced being overtaken by a double-decker bus between a speed camera and a level crossing in a 30mph limit!
Furthermore, in sticking to the limit while preparing to turn right by being in the right hand turn lane, I am regularly undertaken by those who know that there is not a speed camera there and very few traffic police.
Roll on the day that everyone has to retake their driving tests every five years and when all cameras are more discerning by monitoring excessive, inappropriate average speeds rather than only cynical compliance or momentary lapses.
