Regarding the range problem, that is my personal conspiracy theory. It makes a lot of sense but no way that I or anyone can ever prove it.
Theory: Range was never a real problem and car manufacturers seeded that topic to journalists/press, as the companies already had the solution available before communicating the problem.
More range is done with a larger batteries, usually higher quality cells/chemicals. So making the car bigger and more expensive. That’s what manufacturers desire to do and sell anyways.
It never was or is a real problem. They can just charge the customers more and it’s solved.
As I’ve already seen posted, the real problem that cannot be easily solved is the charging time. Right now I ‘charge’ 0% to 100% in 1-2 minutes. No preparation, no special fuel, no special fees or subscriptions, no fuel stations only for specific brands, no apps, summer or winter same 1-2 min, no strain on the fuel tank by filling fast, sometimes waiting lines at the stations but they move quickly with 1-2 min per vehicle.
I don’t see battery or charging tech anywhere close to that in the next 5, 10 or even 20 years.
That’s hard to advance, with decades of research behind us and decades ahead, so car manufacturers focus on their favorite topic: range, where they can just throw their customers money at to solve it immediately.
