I can't believe that in the year 2006 planet earth hasn't come up with a vehicle that actually gets good mileage - like close to 100 mpg. It just seems strange that with all the technology and computers there are no vehicles that get good mileage.

For one, wouldn't the best mpg vehicle be a diesel/wvo hybrid electric? I'm no rocket scientist, but can it really be that hard to design?

Are there any community-designed vehicles out there? I'm tired of waiting for some company to do this. Why can't we?
