As an environmentalist, I'll agree with that.
E85 was never a particularly good idea. It has some good benefits, but not for everyday cars. As we've now discovered.
Even electric isn't without its scars. Check out the Top Gear episode with the Tesla Roadster; Clarkson points out that electricity obviously comes from large energy plants. Which aren't exactly clean.
The balance will come some day. For now, though I'm not crazy about gasoline, I think we're doing better than most people would say. Cars burn ridiculously clean, compared to what they used to. Other sources of emissions should be getting government focus, versus strictly automobiles. It is not the 1970s anymore. My complaint is using foreign sources.
If a water-powered car, with today's technology, were possible as a good option, that's what I'd put my money on for a long-term option. But water isn't the kind of substance that can provide energy as we'd need it to. Again, given current technology. In time, who knows.
