Just saw this on Autocar:

Isn't the point of motorways supposed to let vehicles travel at higher speeds so that people can get to their destinations faster, and make transport more time-efficient?
Also, I think that bit about C02 emissions is just rubbish. What kind of research was that, and how can they be so sure that it'd be the case for all vehicles? And why is the whole world (the UK in particular, from what i've observed) so fixated on C02 emissions? Yes, it is a major contributing factor to climate change, but it surely can't be the only factor?
Even though I live halfway round the world, this does worry me quite a bit, that governments all around the world will follow suit. Coincidentally, I just watched the Doctor Who episode The Sound of Drums (S3 E12), where the British PM (the Doctor's arch-enemy in disguise) goes all loony and tries to bring about the end of the world. Either funnily or scarily, what the UK government is doing now makes me think a lot about that episode...
