All current "electric cars" require a significant battery capacity. These cars are called "enviromentally clean."
Do you want to live next to a battery production factory? How 'bout a battery "recycling" plant? What would you rather be pumped into your house, the stuff that comes out the tailpipe of an XJ or the stuff coming out of a battery plant?
These cars just change where the pollution occurs, compared to a traditional internal-combustion engine. Until we figure out a truly lower-impact form of energy (and I think this won't happen until we drain every last drop of feasibly-obtained oil), I'm not gonna buy a hybrid or "electric" car. Or, for that matter, a hydrogen-powered car.
Why the anti-hydrogen? The output of a hydrogen powered car is water. What's the most effective greenhouse gas? Nope, not CO2 (sorry Al Gore) - it's water vapor. Picture every car currently on the road (plus projected auto growth in places like China and India) spitting out water - seems to me that's a significant increase in water vapor in our atmosphere, which would be a true threat to the global temperature.
Me? I'm going Flintstone - holes cut in the floor. You passengers wanna get to Vail? Fine, start running. Wanna stop so we don't smash into that tree? Fine, slam the feets down and don't stop 'till they're oversized and red. I'm surprised Gore hasn't figured out the benefits of going Flintstone.
