This will kill EV adoption, just to put it into perspective this is the equivalent of an average ICE car (38.6MPG) having 25.5p added per litre of fuel, in a single budget.
The even more ridiculous thing is plug in hybrids are 1.5p per mile, so people with 80+ miles of range in their Golfs etc. will pay half price, even though they are needlessly dragging around an internal combustion engine for 99% of their journeys.
If the EV is driven in the EU, where the UK tax does not apply, how is the UK only mileage reported as it won’t add up to the odometer reading? How is this legitimate avoidance handled vs fiddling the odometer?
