Re: I've been pointing this out for years.
"At 60mpg, that's not much cheaper than diesel. And there's no 70% duty+full rate VAT on leccy!"
A fast charger is an expensive option. It's like the petrol station in the middle of nowhere that charges 2x since they have you by the short ones. You are always better off charging at home/work or a free charger put in by the council if you can. I think there are some shops that will waive the fees if you spend enough money at the store.
