I will jump on the bandwagon and say that I want the performance to be a little better.
The technology is available to make an all electric car (or even like the volt to have a small gas engine running a generator) with great performance. Look at the Tesla roadster. Take that car and give it a long range like the volt can, and I would be thoroughly impressed.
That being said, I still believe burning hydrogen fuel in an internal combustion engine would give us a far greater improvement in technology without a rapid departure of how we transport ourselves.
