To China now, where Old Bill has come up with a cunning ploy to prevent speeding.
In Jiangsu Province traffic cops have set up thin boards showing the rear end of police cars along the side of the road. The idea is that approaching vehicles spot the boards and, thinking it is a real cop car, slow down.
Driver Liu Yuan, who took these snaps, said: "I spotted a police vehicle parked at the roadside from far way. Worried that they may monitor my speed I unconsciously stepped on the brake pedal. But when I passed it I was stunned in seeing from the rear mirror that it's just a thin-plate board resembling a police vehicle." He added "The board even has a solar panel on top, which means the light can flash at night making it look even more real."
