It might get better in about 10 years or so.
That's when the current EVs will have worn out their battery-packs.
The Car industry won't make replacement battery packs for those, because that's less profitable than selling entirely new cars.
Those "Low-battery EVs" will become worthless, and they'll become super-cheap on the second hand market.
That will make it worth refurbishing these by putting in new 3rd-party battery packs, with 3rd party power-controllers.
Refurb-EVs will loose all the fancy features like driver assist and so on, and they won't have crazy acceleration anymore, because 10 year old cars only warrant the most rudimentary possible refurbishment parts.
But there's a reasonably good chance that they won't have any user-betrayal-features either.
