lets face it. most of us drive under 40 miles on a daily basis. Even folks who commute more during the week probably could go gas free on the weekends. I think some auto maker is going to give it a shot.

almost all of us understand that we will probably never fully recover the price of our hybrids in gas savings -but still bought them. We will never save $1000s of dollars on regular maps, but still buy the nav system anyway.

so why would we not pay a couple of thousand extra on top of hybrid prices to get 100mpg??? They could do it now without developing further lightweight batteries.
