I'm thinking that until some break through battery technology is discovered that plug-ins can not go main stream. My guess is that there will be a small niche market for them due to the fact that extra batteries will, I'm only guessing, severely limit the size of the trunk as well as add excess weight to the car.

Trust me, I'd be the first one in line if they can pull it off and maintain reasonable usable space, but I'm skeptical they can go mainstream on the plugin without a battery revolution.

Any post suggesting a more optimistic outlook will serve to make me happy.
