I bet some of you have seen the fixed signs that flash up your actuall speed if your over a set limit, well i encountered a mobile unit yesterday that was flashing drivers speed at them whether they were speeding or not. A guy was sat in an unmarked estate nearby, but i was not sure of the intention of this portable unit.
My detector went crazy so i was travelling at 27 mph when i went passed but was this a chance to catch people for speeding or just a reminder that they may be.
