I wonder what kind of policies China will end up implementing in order to sway people towards green vehicles. It could be a soft touch, or it could be a heavy handed touch. Only something quite dramatic will be able to actually do something to curb their pollution problem. Maybe they can do like some European cities and ban people from driving on certain days based on their license plate numbers. They already have the one child policy, so I can't see how regulating the driving of cars would be too radical. They might not even have to do it long term, but just use it when pollution is really bad to cut down on that smog.
