I can't wait for electric cars to become more common and competitive with conventional cars. I believe we're going to look back car's emissions the same way we look back at the pre-sewage treatment days - when people used to dump their sewage out the window and into their drinking water!

That being said, we haven't reached the EOL for this first generation of electric cars, and figured out what happens next. Will replacement batteries cost a reasonable price? Or will manufacturers use this as an opportunity to try and get you to buy another car? Maybe you'll be able to replace the old battery with a new one from a 3rd party, or maybe you won't because its loaded with DRM.

Battery prices may go down for automakers, but perhaps consumers won't see a huge benefit. A replacement battery for my hybrid still runs a few thousand dollars and its only about 1 kilowatt-hour.
