I think this has cropped up a few times in various threads over the years but from Sky News this morning:

Considering that a move to electric vehicles will, no doubt, over the coming decade or so begin to seriously eat into that £40bn of revenue it is clear something has to be done to plug the hole in public finances left by it (£40bn is roughly what was spend on defence each year for instance). I suppose, personally, it won't really effect me that much as my annual mileage is only around 6,000 miles so it would have to be a very hefty charge to leave me worse of than paying through nose to fill up with petrol every week or so. The ONS reported in 2016 that:
It seems unlikely, to me, that the price per mile will be anywhere near the sort of figures that currently make up the Government's take from a litre of petrol!
I also thought the idea raised by the AA of having an allowance of x,000 miles per year was quite an interesting one as that would probably go a long way to protecting people who are most likely to be significantly disadvantaged by such a compared to paying for it all through petrol and especially those who do live in rural areas (though I can imagine there will be a hell of bunfight over who counts as "rural").
Anyone have any thoughts of their own on this topic?
Rishi Sunak eyes 'pay-by-the-mile' road pricing scheme ahead of £40bn tax threat from electric vehicle drive - report
The idea of "pay-by-the-mile" is back again as the Treasury seeks a way to gradually replace taxes lost through weaker fuel sales.
The idea of a national road pricing scheme has reportedly been revived by the chancellor as the green car revolution applies brakes to £40bn of annual tax revenue.
The Treasury, according to The Times, is exploring ways in which Rishi Sunak can replace lost fuel duty and vehicle excise duty (VED) - known more widely as car tax - as the shift to electric vehicles gathers pace.
Ideas for such a move include a road toll system or "pay-as-you-drive" - a concept last explored by Tony Blair's government in 2007 but abandoned due to opposition from motorists.
The newspaper reported that the chancellor was "very interested" in the idea of a road pricing scheme as ministers accelerate plans to ban the sale of new petrol and diesel vehicles.
The Financial Times has reported that the current 2035 deadline is to be brought forward to 2030 to help reach the government's target of net-zero carbon emissions by 2050.
According to the Institute for Fiscal Studies, fuel duty - frozen since 2011 - brings in around £28bn in a typical year with the balance coming from VAT on fuel sales and VED.
That £40bn tax take is threatened by the environmental goals - hence the drive to find an alternative route for road-related charges.
Because of coronavirus disruption, the year 2020 is not proving a great guide for electric vehicle demand.
But the most recent figures from the Society for Motor Manufacturers and Traders (SMMT) show that almost 76,000 battery electric vehicles have been driven from showrooms in the year to date.
In comparison, more than a million petrol and diesel-powered cars have been sold.
However, the figures do indicate a shift in behaviour as the range of electric models on offer is expanded.
The SMMT stats show a 168% increase in electric sales, while diesel is down more than 50%.
It is a 39% drop in petrol vehicles in the year to date.
The AA has acknowledged that the current roads tax regime poses a threat to the chancellor's income - at a time when Mr Sunak is already under pressure to pay for record peacetime borrowing demanded by the COVID-19 crisis.
The motoring organisation's president, Edmund King, said: "The government can't afford to lose £40bn from fuel duty and car tax when the electric revolution arrives.
"It is always assumed that Road Pricing would be the solution but that has been raised every five years since 1964 and is still perceived by most as a 'poll tax on wheels'."
The AA has supported the idea of an allowance for motorists - with any mile over 3,000 per year being subject to charges and greater freedoms for those in rural areas where there is less public transport.
The Treasury, and Mr Sunak himself, have refused to comment.

The cost of a litre of fuel – where the money goes
The price of fuel can be divided into three sections the cost of the fuel itself (which is made up of the wholesale price, the cost of distributing the fuel and fuel companies’ profit margins); fuel duty (which is charged at a fixed rate of 57.95 pence per litre); and VAT. VAT is charged at 20% of the wholesale price plus the duty, which equates to 16.7% of the final price.
Under normal market conditions, only a fraction of the cost of a litre of petrol ends up in the coffers of fuel retailers. For petrol, at its current average price of £1.04 per litre, just over 72% of the price will go to the exchequer in fuel duty and in Value Added Tax (VAT), leaving only around 28% of ‘wriggle room’ for cutting the price to consumers when the price of crude oil falls.
It seems unlikely, to me, that the price per mile will be anywhere near the sort of figures that currently make up the Government's take from a litre of petrol!
