Watched it. Seemed like mostly happy horse dung from a consultant pumping his own game/book/diet/whatever. If you need a valet team you have a good place to start being less wrong IMO.
I too could've done without the consulting salesmanship, but alas, that seems to be necessary to win any business in consulting.
However, if we can set that aside, what really counts is the content. Is it accurate? Is it useful?
To me, his case for credibility is strengthened by:
1) He not only worked at Tesla, but was in the "Agile at Tesla" team.
2) What he is saying aligns with what we've heard from Elon himself, Munro Live (especially following Sandy + Corey's day at SpaceX) and from other former employees of Tesla and SpaceX who've done public interviews, but with a lot of new detail and color.
3) The information provided offers a reasonable, concrete, ground-level explanation for how Tesla manages to invest capital so efficiently, innovate and adapt so quickly, and avoid the pride/ego/politics/death-by-powerpoint/bureaucracy that slows down so many other companies.
Re: Valet
I think the rationale is that the cost of valet is less than the opportunity cost of employees wasting time finding parking and walking to the building. I currently work here
Boeing Everett Factory - Wikipedia which is similar in size to Tesla's factories, and let me tell you, the parking situation here (before work from home) is a nightmare. On day shift it takes usually 10-20 minutes to go from arriving on campus to reaching your desk. Each way. Valet at Tesla likely has a real-time digital map of where everyone's car is located and where open parking spaces are available, and they might even have software providing optimal routing for reducing overall traffic in the parking lot. Individuals finding their own parking could not do this as effectively if they tried.
