Not because it would save the planet, but because it can 0-60 in 4 seconds AND do it without making any engine noise. I bring you, THE TESLA:
Oh yeah, and it looks GOOD, too!
You want to save the planet by making electric cars? Well, I am not going to debate the ecological and environmental aspects of it here. They aren't relevant to this post. What is relevant is this:
If you want to get people driving hybrid and electric cars, make hybrid and electric cars that people want to drive. The Prius is a nice, comfortable, easy to drive car. A lot of people will want it. But there are a lot of people out there who would never be caught dead driving one - not because it uses electricity, but because it is a dork mobile. Offer consumers choices like the Tesla, and you start to tap in to a whole different market. This is a car a Ferrari driver could embrace. Offer more models, increase production numbers, and costs go down. Pretty soon, you have choices that begin to appeal to the Mustang crowd: people who can't spend six figures on a car, but would happily spend a third of that on a car that looks sharp and goes fast.
As for me, I don't give a rip if the car is good for the planet or not. I want it to go when I hit the accelerator, stop when I hit the brake, turn when I turn the wheel, and do it all comfortably - while looking good. Get the price tag on this baby down to about half what it is now, get the battery capacity up to about double what it is now - both feasible goals as production increases and technology becomes more sophisticated - and I'm buying one.
