This seems odd to me, given that he looks (from the outside at least) to be one of the most ambitious CEO's around. E.g. Building a fulfilment network to compete with Amazon.
I never worked under Tobi directly (or even close), but I was almost always thoroughly impressed with his communication and direction. I think I have a totally different take than the one you stated. The only axis I could see Elon & Tobi both sitting on is being members of the tres comas club.
