Ok, here's the theory...(based, as are most of my theories, on nothing beyond instinct, prejudice, and a profound ignorance of the facts):
Most of a car's overall environmental impact is determined by its lifespan: the environmental damage involved in its manufacture and post-mortem means that longevity is key to its overall, total, environmental impact.
So, after ten years, your Prius battery dies. Are you going to spend more than the car's worth to replace it? No. So the car will become worthless overnight. Priuses, in short, will last only as long as their batteries: about a decade. Whereas most ordinary cars remain economically viable (and so will carry on being used) much longer than that.
So Priuses are, from an environmental point of view, a disaster.
Or are they?
