Re: you focus on EVs were you can

No - the main reason is that it takes about a third as much energy to move a BEV as it does to move an ICE vehicle.

Fuel duty has never brought £30bn to the treasury, it was ~22bn a decade ago, and grew to ~27bn just before the pandemic (I'm not cherry picking pandemic years here).

One of the main reasons for fuel duty is to encourage people to reduce emissions, so there is immediately less need to add it to EV fuel. We should, however, be increasing the duty on petrol/diesel further - and jet fuel (massively).

However let's ignore all that and do some more maths...

The cost per mile (just fuel) is:

38mpg@£1.90 = 22.7p (which includes just 6.3p fuel duty - RAC average cost page)

3.8m/kWh@7.5p = 1.9p (Charging overnight at home - Octopus Go, currently offered rate)

3.8m/kWh@50p = 13.2p (Public charging - Gridserve DC cost)

So... if you subtract the fuel duty (and the VAT on the fuel duty) then you get a cost per ICE mile that is 15.1p, still higher than the already elevated cost of public DC charging.

Assuming that ~90% of miles are charged from home... the typical cost per mile would be 2.4p, so add on the 7.6p of fuel duty and VAT for the treasury - that's now 10p/mile, same revenue for the treasury, but less than half the cost for the user.
