Elon Musk Interview: 1-on-1 with Sandy Munro

I remember my perception changed when I watched an interview with musk talk about the material science challenges of panel gaps on teslas. You can't have that level of knowledge unless you worked very close to the problem. ▶ this video

> are soon switching to 48V, to further reduce low-voltage copper wiring (copper being a 'medium-rare' metal) In an interview by Munro[1] , Elon Musk previously mentioned the desire to switch to 48V together with the desire to use PoE. Combining data and power over the same wires. [1] ▶ this video

Wow so just like all the outsourcing nonsense that first started in the IT industry (and failed) and then crept into all the other industries (and are subsequently failing now) it was all done by stupid MBAs who couldn't think ahead past one quarter. The way that you explained the phenomenon makes me think that there is a business opportunity to capture customers by providing world class service. Auto companies are relearning why it does not make sense to outsource anything that a customer sees or touches. That is your profound knowledge and any supplier that is incentivized to maximize cost per unit will not care one bit about providing anything more that the minimum needed to get the contract. The customer suffers until one automaker breaks the mold and start to differentiate themselves by building in house and having a tighter feedback loop to provide the best quality. Here's how it went down at Tesla straight from the horse's mouth. I remember the skeptics thought he was crazy for bringing this in house but it seems to have worked out. [1]: ▶ this video

I mean, I don't think the dumb tunnel under vegas is good evidence of not being a brilliant engineer. He obviously has a very deep understanding of engineering type shit as well as engineering management[0][1]. He's got engineer brain! Engineer brain can make you do a lot of really stupid shit even if you're a great engineer. That being said I absolutely don't think he's playing 10D chess, he's got a few big Ws and it's gone to his head in a disastrous way. He can be a brilliant engineer/engineering manager and a total fucking idiot at the same time. [0] ▶ this video [1] link

Here you have Dr. Daniel Rasky, a NASA Senior scientist talking about SpaceX and Elon. Daniel Rasky was involved in specific studies that were comparing operation of NASA and private companies. He also has first hand experience from working at SpaceX and with Elon. He is expert on advanced entry systems and thermal protection materials and he was for example involved in decision to select PICA as a heat shield for Dragon, and he explains how that went with Elon. link Here is Elon answering questions of National Academy of Science members about Starship. He explains in detail why he pushed the team towards steel and away from carbon fibers: link Here you have another direct conversation with Elon: link Here is Elon discussing with Sundy Munro mass manufacturing and engineering. Sandy Munro is a veteran engineer from General Motors supplier and directly at Ford. Sandy Munro is now running a consultancy company that tear downs cars and suggests improvements to wide range of clients from the car industry. ▶ this video

>For the same reason. Vehicle seat are, for better or for worse, typically model-specific. Before there was Tesla there was nobody making Tesla seats. Would anybody be surprised if they start outsourcing that soon, given that they now have enough volume to attract third party suppliers and seat manufacturing is certainly not their competitive edge? I doubt this will happen. Here is the reason they started making seats themselves as explained by the big cheese himself: ▶ this video Given what happened when they worked with supplier last time, I doubt they would want to give up the ability to innovate by going back to a supplier even if they are big. Furthermore, I think suppliers might not be chomping at the bit to work with Tesla anymore. When the Model 3 was being developed, that insanely large preorder volumes caused some suppliers to do whatever it took to get the order from Tesla because of FOMO. Some even stripped their margin to the bone in the hopes of establishing a long term relationship with Tesla. In the end Tesla did not deliver on the numbers they promised and this lower volume caused massive financial problems for some suppliers, especially the smaller guys. I think there were even some bankruptcies of smaller outfits. Given Tesla's reputation as difficult to work with, I don't fully think they will get preferential treatment compared to someone like Toyota or Honda (which I hear suppliers love to work with).

In general yes, they solved their manufacturing issues on the Model 3 line and it reached the required speeds and saved the company. See the cashflow turnaround in 2018-2019. They managed to scale that line far beyond their initial targets. However that experience did teach them that their design was flawed and for future vehicles after Model 3 they did switch to large castings anyway rather then traditional welding of stamping. If you are interested in the flaws of the initial Model 3, see this interview with Elon and Sandy Munro where the discuss this: ▶ this video First they had two casting in the back for the wheel area, then moved to one. Now they are moving to replace the whole front. So the new car designs will be two big castings connected by a structural battery pack (yes its removable). Here you see the changes: link The new design: link Example casting: link Here the first press in operation: link Since then they have order many of these, 8 for Berlin for example. This should support around 500k cars production. These custom made for Tesla by IDRA in Italy, they put out a lot information: link Even more information: link They are moving to even larger presses for the Cybertruck.

Any source for that? He sure seems to know very fine detail of almost anything related to the product. See for example: Everyday Astronaut recent Musk interview: link Munro interview with Musk: ▶ this video There are also other examples where Musk talks about things it's hard to imagine of him even being aware of if he's not building anything.

> I think the hardest part about vehicle manufacturing, which is the issue Tesla seems to run into repeatedly, is dependable mass production. Musk agrees substantially. He says prototypes are fun and easy and it's the mass production scaling that is the most hell.[0] [0] ▶ this video

At least in the vid on that page ▶ this video it seems Musk is trying his best. Sadly I'm not a Tesla owner but my Apple stuff works well.

> The main problem as EV manufacturers look to shave weight the batteries are going to become more integrated into the car's structure For those looking for a source, here's Elon Musk saying exactly that to Sandy Munro. ▶ this video

Its not that much faster but Tesla claimed it removes 100s of robots and an incredibly long error prone assembly line. Also, when you weld lots of parts together you have tolerances stack up. Tesla developed its own aluminum that does not need to be heat-treated. It might still need some finishing, but not a very complex process. Check out this video of Musk and Sandy Munro (former Chief Engineer at Ford) talking about it: ▶ this video

I heard Elon Musk state in an interview that they gave every new line of code 1 point and every deleted line of code 2 points so clearly at least Tesla seems to value fewer lines of code. Reference: ▶ this video

Sandy Munro interviewed Elon a week ago, mostly about Tesla engineering. Here's a background video on where they met at SpaceX and highlights of their tour. Here's a link to the interview referenced: ▶ this video

Just watch the interview they used as source. Reading these articles is mostly noise and forcing a narrative ▶ this video
