Isn't the point that using public chargers currently makes most EVs more expensive per mile than an equivalent ICE car? That may not be an issue for most people active on this thread, but it will be for many others.
It's true, but only at one edge of the use spectrum. For most people, the overall cost-per-mile will be a mixture of different charging costs.
I.e., it will be rare for a driver to use ultrafast motorway chargers exclusively. The more likely situation will be charging at home for most of the time, occasionally charging at public chargers in the street or car parks, and occasionally charging at ultrafast chargers at motorway services.
If we take an average cost of (say) 40p per kWh, and an average of 3 or 4 m/kWh, this gives an average cost per mile of 10 to 15 (rounded up) p per mile. Of course, this average will vary widely depending on summer/winter driving, city/motorway driving, etc.
But, again, yes, for those whose driving pattern requires charging solely or mostly at motorway services, the cost per mile will be higher than for an ICE car. However, equally, the Rodney Trotters of this world will never charge the car for anything but the lowest possible tariff...............
