A taxi driver takes a nap in his Volkswagen Jetta taxi on a quiet lane in Beijing around lunchtime, seen not far from the CarNewsChina.com office towers in the capital. The driver’s yellow shirt hangs neatly on the a hook inside the vehicle. Taxi drivers in Beijing are required to wear a yellow shirt since the 2008 Olympic Games. Failing to wear their yellow shirt can result in heavy fines, but the rules don’t say anything about napping time.
