So, you are happy for people to be able to buy powerful cars, that emit a lot of various pollutants, drive them into Central London, thus adding to the pollution and traffic already there, and effectively ensuring that if their own powerful cars stay in London, they will never be used for their full potential?

I don't agree with a lot Livingstone says (in fact, generally I find him smarmy to the point he is offensive), but I do agree that we need to be persuading people not to drive if it is not necessary.

Make no mistake, Porsche are not doing this for their customers. They are worried that some customers will start to wonder if they really need a new Porsche if they are going to continue to get caned by taxes.
