Is that £1.50 at motorway prices though? (genuine question, I like comparing apples with apples, it’s easier). However, that does, just, show EVs to be cheaper (skin of teeth here).
Petrol is £1.41 in town here. At the service station quater of a mile before the slip road leading onto the M4 petrol is £1.44. I could fill up just before I got on the motorway and drive 400 miles. In the unlikely event I need to top up I can jump off the motorway to a local fuel station with cheaper prices, just like you could in an EV.
That said my car is not economical to run at all @£1.41 litre £6.415gallon costs me 22p per mile ?
