Electric cars - discuss

Well, you might have noticed a phone induction charger barely works if the phone is in a thick rubber case; it needs very close coupling to make an efficient magnetic connection.  So one basic problem in getting a kilowatt or so from the road to the car is the car's ground clearance.  Roads emitting very powerful and loosely constrained magnetic fields like that would probably be lethal to anyone fitted with a pacemaker quite apart from the massive electrical interference to all sorts of other equipment.
