Parking at work or shop etc, plugging in, tapping your card then going about your business is slightly quicker and is much cheaper than refueling. Once a week for an average mileage/ in an average leaf (some excellent deals on these albeit the ugly sister). Everyone spends over 40 mins somewhere every week with a charger (download one of the charger map apps and be surprised how many there actually are). And if you have a drive like most do, even easier.... Although I did it without for a couple years. I understand people are used to ICE and will take longer to convert, but will have to one day as ICE fuels will not last forever, where as refuelling a car with renewable energy.... Im not a gaffer on a big salary, just a normal bloke on the lines and I'm certainly enjoying the overall cost savings.
