Fantastic example of lack of joined up thinking in government. I've just converted my car to LPG, so I need a new tax disc. The DVLA needs to see my old tax disc. I can't send them the original because I need it in my car. But they won't let me post a photocopy. They insist I have to drive to the local office in Borehamwood, take the disc in, swap it, and drive home again.
Seeing as half the reason for converting to LPG was to save emissions, this seems particularly bizarre. And it's a great example of the need to overhaul government regulations to make it easier for everyone to be green.
