We can only guess at what improvements to battery/charging technology and the cost thereof which may occur between now and whenever this happens but I think I can safely predict that our glorious leaders, the great and the good and their mates won't find themselves regularly in need of convenient charging facilities. Us mere taxpayers, on the other hand, will likely find ourselves scrabbling around trying to find communal charge points which a free and working when we actually need them. Will these be easy to find and cheap to use I wonder?...
