A very good assessment of the limitations of a young technology.
However I will say that electricity is easier to transport than fossil fuels. That being said the internal combustion engine will be with us for a while I am sure.
External combustion engine?

They have EV'S in northern BC, the winter temps go down to -30 or more, the EVS are useless, do not get a full trip on one charge, and useless in deep snow or snow covered roads. and I would not want to travel at night for a long distance in _-30 to -45 , gas vehicles are safer and you can get gas everywhere.
