I've lost count now of the amount of people I've had this row with. Someone will tell me again that it's good for the environment to incentivise drivers to scrap their old cars and buy brand new ones, so I might as well say what I have to say on the matter here so I can just wearily point at it.
This is not an environmental policy, it's an economic one. It's meant to kickstart the auto trade, not save the planet. Just stop and think about it for a minute and you'll see... I would love to have the figures on how long you would have to drive a cleaner car to offset the environmental cost of the manufacture of it.
It's just another sop, a near meaningless salve to our consciences while we blithely continue to destroy the planet, like the recycling industry. Actually worse. At least recycling does lead to some reduction in mining and refining, even if it is infinitely better to reduce packaging in the first place or come up with ways to reuse materials.
I'm not claiming to be blameless. I love driving, I drink pop from plastic bottles, I'm a filthy consumer just as much as anyone. I just wish everyone would be a bit more honest about it.
