that's true. but you've got transmission losses. transformer losses. charger losses. not all the charge going into a battery comes out losses. motors aren't 100%. i'd also be interested to find out quite how much less mass than a diesel engine are a car's worth of batteries.
additionally, my camera, rechargeable drill and anything else with rechargeable batteries don't seem to have the lifetime that's claimed for them, whilst my motor engineer tells of skoda taxis with 400,000 miles on them.
my knowledge of physics leads me to believe that taking 1400kg of machine around with you is a good way to waste energy whether that energy has been burnt inside or outside of car. public transport, walking and cycling has a future - not cars
