Perhaps we should have his discussion around electric cars that the world and his wife seem to lauding as eco friendly, notwithstanding the whole life environmental cost of mining, manufacture and recycling. I'm no expert and haven't delved deeply into it but with an old diesel car (bought when the government were encouraging diesel cars) doing about 3K miles a year I'm not in the market to spend out on an expensive leccy one.
