Hybrids don't ever make up for their cost either but... people don't like to pay at the pump. the little turbo diesels will sell because not only do they get better mileage but... they are tougher and last longer (maybe not as big a deal as it used to be).. and they don't have the complex and semi annual smog checks here.
They also are not gutless wussy cars like the hybrids.
I don't care.. for a few more bucks on a long trip I take my Lincoln.. 23 mpg but it is very comfortable. I owe nothing on the car.
I forsee solar panel development and other things that will make electric power very cheap. I see myself with a little electric hot rod and then my big car... a motorcycle and maybe a 10 mpg hot rod or two. I see things working out fine.
I think the more gas costs the more private industry will get on the stick and make things happen...
The people who like doom and gloom and like to sit on their butt and wail for big government to save em make me sick.
