No clue. It's by no means unsolvable (simply charging at off peak times should suffice in many areas), but it does remain true that electricity that goes to the oil refinery can't necessarily make it to a house.
I'd much rather we let people not drive at all if they want to as a way of reducing the strain, as well as allowing LEVs or small electric cars on the road for the people that don't insist that they need to tow a boat and a caravan up a mountain at 20 over the speed limit 200km away with a pallet of plywood to drop their kids off at school.
