Another rumor is that the Prius is dirtier than a Hummer in terms of TOTAL pollution (batteries).
Being a leftist means never having to deal with the consequences of your actions, as long as you "meant well." For example, look at the disaster of MBTE. An oxygenator to help cut down on smog. Never mind that it's water soluable, which means that when it leaks out of the underground tanks, it pollutes the water table and is damned near impossible to get out of the water supply. So we have "cleaner" air, but can no longer drink the water.
Is anyone surprised? And these are the "experts" who are going to write laws to save us from "Global Climate Change!"

You left out one itty, bitty detail... MTBEs are carcinogenic...
