Is there any evidence of this, outside of him personally claiming this to be the case?
I'm too lazy to track down more right now. I don't know of anyone claiming (with evidence) that he doesn't.
In his biography there's interviews with people inside and out of spacex/tesla talking about it that are pretty convincing.
I already know the mythology surrounding his engineering credentials. But I think perpetuating it does a real disservice to the real engineers doing work on these products. Do people really think that a bright, "well read" physics undergraduate can lead the practical engineering work on rockets and cars? I find it hard to believe.
Most people do not. Don't blame Musk for missing that memo. :P
(By the way: the book Mindset by Carol Dweck might be an eye-opener...)
I'm sure Elon sticks himself into tons of meetings, and hence has a lot of knowledge about what's discussed. And I don't doubt that he sets the goals for the engineers to meet, makes aesthetic and design decisions like some of the interviews suggest. But I think the guys Mueller manages are the people who actually make Falcons fly.
Just look at the $35k Tesla that he pulled off by kicking out sales. A regular CEO wouldn't have done that. With all the chaos it has caused, Elon understands that at this point price is the most important part in the decision for buying a Tesla for lots of people, and paying sales just hinders selling.
You know that's reversed right? https://paloaltoonline.com/news/2019/03/11/tesla-puts-brakes...

Can you do that without a tesla.com email address ?
Hate the guy for his personality all you want; I can certainly understand why. But there's no need to downplay his achievements or skills.
[1]Presumably, if he's down on the factory floor looking at things, he should be wearing a hard hat, so good for him. If he's bolting together cars himself, that's probably marketing.
That settles it then. Is it a yellow hardhat?
Is his salary in any way tied to touting Elon Musk?
He just hit the fortune with PayPal. The other stuff (his "involvement" in engineering etc) is the classic media hagiography of powerful CEOs.
>He borrowed all of my college texts on rocket propulsion when we first started working together in 2001. We also hired as many of my colleagues in the rocket and spacecraft business that were willing to consult with him. ... I found out later that he was talking to a bunch of other people about rocket designs and collaborating on some spreadsheet level systems designs for launchers. Once our dealings with the Russians fell apart, he decided to build his own rocket and this was the genesis of SpaceX.
Additional info from Jim from a follow-up interview[2]:
>Cantrell ... loaned him some textbooks to study. The books were "Rocket Propulsion Elements," "Aerothermodynamics of Gas Turbine and Rocket Propulsion," "Fundamentals of Astrodynamics," and the "International Reference Guide to Space Launch Systems." He would quote passages verbatim from these books. He became very conversant in the material. ... Musk would absorb this information and then hold his own in conversations — and he didn't hold back.
Additionally, Ashlee Vance's biography [3] describes his day-to-day as "quite involved with rocket design" at SpaceX and goes into a lot of detail about spending time on the floor assisting SpaceX scientists with their designs.
Obviously any single person at a company the size of SpaceX doesn't individually design and build a rocket by themselves, but it's generally agreed upon that Elon is knowledgeable in rocket science and contributes many ideas to the designs.

If Musk slipped in the shower and cracked his head, life (for the companies) would go on.
