Market saturation?
Yep. As others have observed, those for whom they ‘worked’, either from an economic standpoint or as a means to satisfy their desire to virtue signal, have already purchased them. If, as we were lectured, EV’s were so damned amazing, the market would have responded accordingly; they are not, and so the market fizzled. They seem to have a place for some applications, but not as a replacement for internal combusion engined vehicles enjoyed by most. But the globalist ‘elite’ are just fine with that. The sooner they can get us into our walled cities only occasionally zipping around in golf carts while they run the world for us, the better.
