Actually, I look at the e-car phenomena a bit differently.
I figure the government should 'butt out' ! Don't help them or hinder them..let them find their level.

They seem to be working, at least for the Tesla owners I know. ..Besides, i wouldn't even pretend to be anywhere near as smart as Elon Musk !
Back in the first century, some locals were troubled by the new sect called "Christians". They were so upset that they wanted to do the Christians violence.
However, there was an old Rabbi named Gamaliel, who gave some very sage advice..and I believe it is still a great way to view things, and very applicable to many things today.
Here's how he put it !
38“So in the present case, I say to you, stay away from these men and let them alone, for if this plan or action is of men, it will be overthrown; 39but if it is of God, you will not be able to overthrow them; or else you may even be found fighting against God.” (Acts 5:38,39)
