The other problem with going to electric cars is that you put further dependence on an energy source that is hardly overflowing with an abundant supply, granted electricity can be generated through more sources like the gigantic three-bladed windmills that are popping up everywhere where I was going to college, nuclear, coal, water dams, solar, etc. My concern is it would make powering our houses and computers more insanely expensive to run. Another problem is when you have ice storms that knock out the power for a week, then your really up a creek.
