Therefore the subject of electric cars was on a lot of people's minds because of California.

It just happened to work for him because electric cars show the basic ingredients of a disruptive technology. There is no way in hell that they meet the minimum needs for a car today. Yet projected rates of technological development make it clear that they will do so, and not that far from now.

GM wiped out by someone currently manufacturing electric golf carts or dune buggies? Don't laugh. It could happen. Hell, Honda did it to the traditional motorcycle makers after establishing themselves with dirt bikes (though Harley did manage to survive in a high-end niche).
