So what you are saying is that depreciation on electric vehicles is terrible. So maybe what we're actually saying is "No one in their right mind would buy a new one............................".
As for the comment made about a nationalised EV charger scheme there certainly needs to be some government support and intervention. If you understand how private enterprise works you'll realise that these things will be planted where they'll make the most money so London, Leeds, Manchester will have shed loads of the things whilst there will be charger deserts elsewhere. Some levelling up required methinks.
Nah, EV's were just holding money, and lots of them were selling over list (that was never going to last), so now they've come back to parity/ true worth. There was massive demand, but supply couldn't keep up, so used prices got jacked, but supply of new has caught up now, so 2nd hand has to naturally depreciate.
Plus loads of the early adopters now have EV's which are 2-3 years old, and as they like/ want newer cars/ tech they're swapping those for new EV's, they're not going back to ICE. Lots of them did this as their PCP's, leases or whatever came to an end so, it's a natural time to swap (for them).
The key indicator, is asking what people who have owned EV's are going to buy next, they're the ones with the most experience, and where you're likely to find the most truthful results. 95% of people wouldn't be buying another EV if it was costing more or they didn't like it, they're not going to buy on to try and prove a point to someone on a forum, they do what makes sense. Some of those going back to ICE might have been put off by high electric prices but these have come right down again now, and electric is super cheap on the right tariff. More are moving over to EV than are moving back to ICE from EV though, that's for sure.
Even a lot of the gullible have learned to cut through the lies and mistruths now, but some are slower than others. They may get there eventually.
As for chargers, they need to put a price cap on the unit cost, but I imagine the reason they are not doing this yet is that the private companies are paying for the infrastructure and grid connections etc. Even though the charging companies are making money per unit, they're still likely making a massive loss overall, and will do until the infrastructure cost has been covered. The unit cost should not make a massive difference to most EV owners at the minute though, as nearly all of them charge at home.
This is also why they probably won't role out the publicly owned chargers, as they'll have to pay the cost for the infrastructure, which they won't want the initial outlay for something which may eventually become largely redundant. They will probably just construct more power generation, so they make the money at source, not in distribution.
Once EV's make it to those who can't currently charge at home, the all the infrastructure for public chargers will already largely be in place (probably around 2030), so the government won't need to let them charge high prices at the pump and make a killing on that (as the infrastructure will be paid off by then), they will just want to tax it instead.
After 2030 there will probably be more of a shift to enabling home charging for those who can't easily install a home socket. So will be something like public street chargers, maybe somehow linked to their electric bill or some other reasonable tariff.
Then once most ICE cars are gone or are massively outnumbered, they will massive jack up the tax on electric used for car charging, or introduce a milage tax (on all vehicles, regardless of fuel system).

As things stand, and I live in hope of further developments and improvements, we are heading for a 2 tier society when it comes to personal transport.
