Battery tech continues to dramatically improve and EV cars are coming back. These early "modern" EV cars you mention were simply ahead of their time, IMO.
It's hard for me to see a conspiracy here having only modest knowledge of battery technology and the coming EV wave.
Many other "green" techs are also growing, spreading and being practically applied around the world. I guess "big oil" has dropped the ball in a very big way?
It would be shrewd for oil related businesses to become involved with these new energy technologies, yes? Wasn't that guy in the video with his gererator from oil country anyways?
FWIW.
Best,

P.S.: Most, if not all, big oil companies are held by millions upon millions of public shareholders and have very little concentration of ownership at management levels. Old ladies, folks with 401ks and people like you and me are "big oil".
