One day last July, Michael Thompson was driving in his car in Grimsby. He noticed a mobile speed camera. He also saw that many oncoming cars seemed to be speeding. He flashed those cars to warn them to slow down. It is not known whether any of the cars did slow down but, if so, the road was presumably safer for them reducing their speed and the public interest in drivers staying within the speed limit was achieved. Indeed, he later said that he was trying to warn motorists to prevent them from braking dangerously when they saw the speed trap.
