Whether it is Iain Carson’s comment piece in today’s Guardian – Only stiff rules will drive car makers to see past the petrol – or GM’s likely sale of Hummer, there’s a point being missed across the board.

What car makers and car drivers need is a stable fuel price that does not distort the market with artificially cheap domestic electricity and gas… or artificially expensive petrol and diesel.

Most people are too busy complaining about turning timber waste into biofuel to see the wood for the trees.

If CO2 is the issue, and it’s certainly the political one, then it’s ridiculous that plug-in hybrids are suddenly viable simply because the oil price is high - it has dropped by nearly 10% over the last fortnight, incidentally.

If we all start recharging our electric vehicles at home, then the tax on and cost of electricity will rise enormously and we’ll end up buying incredibly cheap, second-hand V8 saloons.
