Who killed the electric car? is a great movie to show friends and introduce to electric cars. I'm so glad it exists, and is such a useful tool. On a similar note, anyone who liked the movie should check out the book
"Two Cents Per Mile" by Nevres Cefo . It expands on the movie (the NiMH / Chevron scandal), as well as providing more general information about electric vehicles, and comparisons to combustion vehicles and other alternatives.
