Re: A bit out of date?
1) HMRC right now is like the music CD industry around 2008 or so: they can see that the revenue from petrol/diesel is going to die, but refuse to acknowledge it might happen.
2) Given that their reports tend to be at least 2 years out of date you should expect another 2 - 3 years before seeing any real improvement in public charging points.
3) Apropos 2 above there should be a caveat as HMRC is undoubtedly trying to work out a way of generating the lost fossil fuel/ICE income. Possibly high EV car taxes earnestly labelled as "environmental taxes"?
