1) Those things are butt-ugly. I would never touch one.
2) The thing many people (some people in this thread come close) are missing, is that electric cars are overall worse for the environment. I don't mean in the metal or the manufacturing, I mean in terms of actually driving, more pollution is indirectly produced by an electric vehicle:
Let's start with a little bit of gasoline.
We can do 2 things with this gas; we can put it into a car, or we can send it to a power plant.
In the car, a few milliliters of gas are injected into the air, ignited, burned cleanly, and the expanding gas directly pushes the wheels (After a few gears and such, of course).
In a power plant, the gas (far more per second) is burned, this makes heat, which boils water (somewhat inefficient), which becomes steam (incredibly easily compressed compared to water), which turns a generator (mechanical friction loses energy), which goes to a transformer and power lines (a little power lost to heat, though the massive voltage minimizes this), which goes to your car, which turns generators (more energy lost to mechanical friction).
If nuclear-, hydro-, or wind-power were more widely used, then electric cars may become less damaging, but until then, stick with your gas guzzler; at least it doesn't burn gas by the barrel.
