Hybrids for insterstate commuting did not make much sense when I looked into it a while ago, and I think there are more hidden energy costs to make the batteries that people are not aware of. I think there is a better than fair chance the past analyses may be blown out of the water by increases in the cost of oil due to rising demand and lack of refining capacity.

When you are dealing with City driving, you simply can't beat the hybrids, plus they are smaller and easier to park. The real potential for this technology is for buses. I ran into some guy who designs these for public transit, and the energy being saved is stunning, because it takes a ton of energy to stop a bus and they stop every few hundred yards.
