I guess this is something to do with saving the planet. But quite frankly they can shut up and go away:
Nick Clegg’s party has unveiled proposals to only allow ultra-low carbon vehicles on UK roads by 2040.
The controversial measures would mean millions of petrol and diesel cars being forbidden.
Only electric vehicles and ultra-efficient hybrid cars would be allowed on UK roads under the Lib Dem plans.
What is it about these so-called 'liberals' that makes them want to ban things, stop things and generally restrain and curtail the liberty of ordinary Brits?
