Amazing isn't it....but it has spurred BMW and also Audi with a new low emissions A8 into action so it's justified itself. It only applies to cars bought since the beginning of this year, though there is talk it may include all vehicles over 3.0 engine capacity that are over 6 years old.

They are also going to use emissions for raod pricing too in the UK. There is talk of a congestion charge in NYC I believe.....it will spread to many cities over the next few years.
