The 'lost' revenue to electric cars is a bit of a misnomer for me when taxes are so high. Proportionately more revenue is extracted from the economy as a whole than ever before. It's who is sharing the burden that could be addressed. The irony is that it's those that are relatively well off that have received the tax advantages and incentives to go electric. I never understood why for years people who could afford a £100k+ Tesla got free road tax, thousands of pounds in grants towards the cost of buying the car and grants to install charging equipment. But that's all water under the bridge.
The revenue takes about £5bn in VED and £25bn in fuel duty (yet the gov only spends about £9bn maintaining the roads) - so it'd make more sense to keep chipping away at fuel duty - which if you think about it is a road pricing scheme in itself - you use your car, you need more fuel, you buy more fuel, you pay more fuel duty.
There is also the fairness issue. These schemes are often dreamt up by civil servants and activists that live in major cities where everything is on their doorstep and they hardly ever use a car (or even own one). The practical reality for the millions of people that depend on the car means taking journeys on a regular basis.
