Or maybe he sees the writing on the wall for the future of EVs, it isn't EVs, its HEVs, that will be the final solution, no batteries needed, just hydrogen.
If Musk has any sense he will fund research needed to achieve room temperature hydrogen liquification. Looks to me like that has never been seriously attempted due to all research on it being defunded, because nearly all research on it has been by fossil fueled interests, and last thing they want is a fuel with three times the energy density of their usual product cannibalising existing sales.
If it was achieved it would be a world's first, and it would be the energy link needed to link the energy of the sun to aerospace, via widespread domestic and community solar hydrogen.
The link needed then between all people and the energy of the sun is money issued for all the product created including all the hydrogen, in fact anything that isn't heat, because all of it exclusively reduces entropy when done from the sun, therefore reduces global temperature, and therefore has indusputable intrinsic value.
Knowledge of the Energy Polarity Multiplier Framework is needed to understand this.
Its in an Amzon book of that name.
Suggest you should buy it.
Would appreciate a review of it including in Medium, if you see the value in it, would be cool, literally, for all of us.
