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.
Fairness and equality are different words and mean different things, you also cut off the second half of that quote in an attempt to prove your point.
