This article in Salon:
...explains the difference between a regular hybrid, a plug-in hybrid, and an all-electric. I guess, not having paid too much attention to hybrids (I'd love one, but when you're on a used-car-only budget, you don't get that option), I had assumed they already -were- plug-ins. Which was why the previous article confused me so much.
The one argument I have with the article - the writer says that a 40-mile-per-day capacity really isn't needed; most people drive less than that. Do I really commute that much farther than the average person? My drive is somewhere between 17 - 20 miles one way. So I easily do more than 40 miles a day, especially once you add a grocery store trip, or picking a kid up from school or a friend's house, or any of the other million errands that seem to come up every week...
