I don't think there will be very many foreigners actually driving here - China does not recognise International licenses. So we will be relying on taxis, which will be interesting in itself.
Road crossing will be exciting, but on this trip to Beijing, I felt more pedestrians and drivers were obeying the lights. I also figure that most of the visitors will be in the 'tourist friendly' areas - not out in the more remote/rural suburbs, so traffic rules may be more obeyed.
