It does annoy when the answer to how expensive public charging is, is 'oh you should never use a public charger' and that you should always charge at home on your special rate from your bank of solar panels. That's all very well, but over 75% of all car users in the uk will never have the ability to charge their EVs at home due to not having off street parking, or living in a flat, or living in rented property etc . So we are basically saying that if you are rich, own your own house, have nice off street parking and charging facility then running an EV is cheap, however if your poor then you have to pay 6x more per mile....
