I'm confused by this. A million mile battery would make ICEs obsolete today. It would be more cost effective to spend $50k on a Tesla Model 3 than to buy 5 Hyundai i10 and driving those to dust.
A 1 million mile battery is kinda like fusion. Once it happens there is no going back so I don't think that failing to solve this problem is a blow to EVs.
Musk says modern Tesla's are designed to last a million miles because he wants them all to become taxi's. Full self driving taxi's that return more then they cost to the owner after Tesla takes it's take from the taxi earnings.
I don't know whether to believe this, but he has the motive, opportunity, and is definitely present at the crime scene.
