The answer i keep looking for, and never seeing is - what will my electric car do to my electric bill? I'd much rather pay double for gas than triple for electricity. I can see the electric companies drooling over this now.
Basically, if its going to cost me more money than what I already spend, I don't want it. Since I never hear about its going to save me money, or cost no more, I can (probably) safely assume that its going to cost me a lot more.
