This should be widely welcomed as it fits in with the drive to eliminate private cars from the major cities. There are 2 ways at least of examining it...........it might coincide with the alleged conspiracy of the dumbing down of the taxi test and it appeases certain elements claiming we're entirely responsible for toxic pollutants in China etc. Personally, I see it as a good thing in general terms despite the need for more taxis if it becomes a roaring success.
