Points 4, 6, and 7 are a pretty compelling argument for electric cars, at least in cities (plus the shifting of exhaust outside the city).
I just find it difficult to believe that converting three times (electricity source -> electricty -> storage -> mechanical energy) is going to be more efficient than converting once (gasoline -> mechanical).
