I for one love high mileage vehicles, I just don't like government regulations that push the industry in one direction or another.
As a family, we drive less than 12k a year (1 car) and recently changed from a Mazda3 to a Jeep Compass (MPG hit, but man do we have more space!
If/when we drive more, I think I'll start looking at diesel cars. Living in NE, I don't think the cold weather works as well with a battery. Plus, it just seems like 'hybrids' are over priced.
