According to my former student there were some real technical deficiencies that doomed them right from the beginning. It was all because the stupid California legislature mandated 10% of cars on the road had to be EVs without bothering to check whether they were even possible.
Ah, and this is the consistent problem these days with people, both general and political.
Today, everyone thinks everything is possible. Seems polar opposite of 100+ years ago where nothing was possible ("get a horse", "it'll never fly").
You know the dictum about "you can't legislate morality"? Well, alot of that is hogwash, but a solid truth to tell these know-nothing morons is "you can't legislate technological progress"!
