To be fair, the biggest thing that people say the british government are bad at is fixing the economy; although in all honesty they can't be said to have caused it in the first place.
Next time you see a Bentley leaving a Northern Rock car park, hit him as hard as you can in your Hummer.
That being said - you can't drive a Hummer in london anymore really; it scares the hippies and you'll probably incur some kind of congestion charge discrimination and/or not be able to fit in any of the spaces.
