I don't think anyone here is going to argue the fact that oil is a finite resource and something needs to be done to reduce our dependancy on it. Hopefully sooner rather than later.
Many of the new vehicles are rated to run on either pure gasoline or the gas/ethanol E85 mixture. I think some can even run on pure ethanol. It's not much, but it is a beginning as it will reduce (somewhat) our dependency on oil. The main problem right now is finding places to purchase that type of fuel, at least around here where I live. I just recently read that they are building 2 (or possibly 3) new processing plants in our state for producing the Ethanol blends, but they won't be operational for a year or two.
The E85 looks like nothing more than a sop to lentil-eaters in my view. The complete lack of an infrastructure to support it undermines it before it gets underway, and there simply are not sufficient incentives for buyers to stump up the extra in the first place.
There are also the electric cars. I think more people would be willing to buy those if they didn't make them look so stupid.

Why can't they just make them look like regular cars, so people can't tell when you're driving down the road that you are definitely driving a goofy-looking electric car? And then the automakers complain that they are having a hard time moving the electric or hybrid cars and they don't seem to "get it" that it is because of the way they look. I was watching the news a day or two ago and saw that a company out in Silicon Valley in California had produced an electric sports car. It looked pretty neat, definitely something I would consider buying if I were in the market for a sports car. The only problem was the $100,000 price tag.

Although, they did mention that they had a 4-door sedan in the works that would carry a smaller price tag and still look sporty-ish. Hopefully that will make the "big boys" in Detroit stand up and take notice.
