Riding a Brompton with a power meter.
At 8K miles a year at 42mpg, which is very average, I would use 2594 litres over three years, which is £3800 pounds. For an EV that might be ~£1000.
Most EVs seems to be 20% - 25% more expensive than equivalents. e.g. Volvo XC40 petrol vs electric £38k vs £48k or the petrol Nissan Qashqai vs the electric Nissa Ariya £31k vs £41k
That's more than ten years to break even for a typical driver.
You have to consider what the resale market for ICE cars will be like in the 2030s. The long term depreciation on new ones is going to be horrific.
