The thing that concerns me is how much of the cost of petrol is made up of fuel tax and VAT. If it weren't for that, the stuff would be ridiculously cheap. Electricity isn't being subjected to any fuel tax, and VAT is lower on electricity used to charge cars at home. If we look at a level playing field, that is excluding any taxes, it's a very different story. If electricity for powering cars was taxed at the same rate as petrol for powering cars, electricity would be the unaffordable one.
And with the rise in EV ownership, there will come a point at which the government will feel the pinch of lost revenues. And then will they be coming for us?
