Re: @uncle sjohie (and others)
"Many people already go to the supermarket, or workplace, or retail park, anyway."
Yes, but how many places have charging points? And two out of three examples you have given are shopping areas - how are they going to pay for the installation? Oh, of course, they aren't - YOU, the customer are! Expensive retrofits of high current charging points will ultimately be paid for by the shopper.
As a point, my local Costco has electric charging points. I have NEVER seen these being used.
"That'll really go down well with people that "don't want to be restricted". Especially those not on a usable public transport route, but who already drive to supermarket, workplace, retail park, etc."
And the moral is - don't get an electric car!
