The theory is if you avoid the little white lines on the road you can"t be prosecuted. But police say the potentially deadly manoeuvre does not work - the lens will snap your plate whichever side of the road you"re on. What"s more, offenders may face further charges for dangerous driving.

News of the high-risk strategy comes from the West Yorkshire Casualty Reduction Partnership, which monitors local Gatsos. Spokesman Philip Gwynne said they"d filmed a number of near misses. He told us: "Drivers pulling out of side streets won"t be looking for vehicles coming from the wrong direction, and neither will pedestrians crossing the road."
