Re: 50 miles???
Most 'charging locations' have one or two chargers which need to be occupied for 30-60 minutes to achieve a charge. In reality, most of them are in car parks and are occupied by one car per day.
My village petrol station has 12 pumps and services ~1,000 vehicles a day. There are several supermarkets within 10 miles that do an order of magnitude more business.
