It's basic supply and demand - the sales are tanking, and without subsidies nobody will buy them, and the car companies are realizing that.
A few models (Teslas, for example) do okay with the upper class, but the lower and middle class can't afford them, don't have anywhere to charge them, and have to drive too much to depend on them.
Even in a trendy, wealthy city like Boulder, CO which is all about saving the environment and going green there isn't nearly enough charging capacity for everybody to use EVs.
An EV is better than no car at all, but they're a downgrade from an ICE in most cases.
