x100! I saw a commercial the other day for the Chevy Volt (or maybe it was that new Chevy Sonic, can't recall) and it said you could go 35 miles on electric.........35 miles!!!!!! I'd always be afraid of running out of juice on a pure electric car, and the hybrid's you have to flip over to gas...so I agree with Paul....you're still using gas, and electricity that had to be made at a power station. And many many charging stations would have to be built before I'd feel comfortable.
I'm all for alternatives, and definitely want to be free of the hold OPEC has on us for their oil, but just don't think we're there yet......neither in design or infrastructure.
