The 'Nanny Staters' are at it again. According to THIS story on Guardian Online, car manufacturers will now have to devote 20% of the space of their adverts (or time) to explaining how much pollution they cause. You know, if people want to know about that it's perfectly easy to read in the car's manual. It's stated very prominently in most of them.
Anybody with half a brain knows that cars cause pollution. And anyone who is concerned about that will ensure that they buy a car which they're happy with. When I ordered my new car I made sure I knew what the emissions were before I placed the order. The salesman told me that most people now ask the same question and that it wouldn't be long before Audi were forced, by customer demand, to produce their own version of the Prius. They needn't bother on my account, but it proves that customers are, as ever in a free economy, making their own informed choices. What we do not need are do-gooders telling us that we should feel guilty for driving cars. For many people cars are a necessity, not a luxury.
