I was discussing EVcharging with a mate a while ago and I can see some sort of valet parking having to be used in area's like Blackpool in the summer. They have a massive car park that holds several thousand cars and it does get full, now I live 55 miles away so in all probability I would not be able to drive there and back on one charge, but what if there are no charging points available, people are not going to park up, put their car on charge and then walk back from the other end of the town to move their car, people are just too selfish, so it is either going to need some kind of valet parking, were they move cars once charged, or there's going to be a lot of people stuck in places like blackpool with flat batteries.
On the subject of earthing I can see that being fraught with problems too, if they are 'rodded', then what happens if the only place to install the charger is within reach of some metal part of the buildings structure, again if two points are installed, both with rods, what about sphere's of infuence between the rods, step potential etc, in my opinion the whole thing, as usual has clearly not been thought through.
