Former Tesla engineers revealed inconvenient truths in the manufacturing process of Tesla vehicles


by Maurizio Pesce

A person who was a former Tesla software engineer is doing a naked confession about his past work at the sub forum in the sub forum of the bulletin board " The Something Awful Forums ". Confession that it was tedious content with engineers 'viewpoints, such as how to install Tesla car's firmware, is attracting a lot of browsers' attention, and AMA (Ask Me Anything) to answer questions is being done.

The full screen shot of Mr. "fart-powered cars" written by former Tesla employee is summarized in the following tweets.

ato̧̕m͡i̴̷̛c̨͝t͝҉͡h̷҉u̵ - M͜͞b͏͝s' tweet: "A former Tesla employee, who worked on their IT infrastructure, is posting in a subforum of a subforum, a little-known place for funy computer forgotten by time.

Mr. fart-powered cars who was enrolled in Tesla once said he was writing infotainment firmware and backend service code. It seems that all these services were executed at the bottom of one data center. Writing started "Contribution has started from the content that" junkins pipeline once caused a restart hell of nearly 1 hour ". The NDA (confidentiality agreement) that Mr. fart-powered cars tied with Tesla is said to have expired.


According to fart-powered cars, model S and model X are communicating with the backend using OpenVPN. At its backend there is a metadata service that sends information to the system. One of them said there is a Json payload made with the worst system of about 20 MB describing the supercharger in the touch screen. However, it is said that rebooting of components frequently occurred, as programmers who used to create a system forgot to add a custom parser authentication code to prevent segmentation violations. Mr. fart-powered cars says that such a malfunction can not be totally enumerated.


The question continued to Mr. fart-powered cars. In response to the question "Why does the car run Ubuntu's VMS cluster?", "It was Centos 6 and Ruby on Rails in the past, I have not worked for three years, but for models S and model X I heard that it is not model 3. Model 3 uses new technology, but it is based on the same data center. "


When I was in charge of model S program, fart-powered cars writes the surprising contents that "software engineers got into the car running on the line in order to replace the firmware".


In response to the question "Can not rewrite storage before installing on a car?", "Since a complicated component is incorporated in a car and special procedures are required for updating, sometimes Tesla did not choose to rewrite the firmware before assembling, as it took more than 10 trials. "


Finally Tesla got "smart", so it is said that it has been improved in the model 3 manufacturing process.


The production method of "Tesla flow" seems to have been surprising for many engineers looking at bulletin boards, so I was asked "Is Tesla never heard of the term" process engineering "?" . In response, Mr. fart-powered cars said, "Every smart engineer quits or gets fired, but a negative" legacy "is not their fault," said a technician who is afraid of "changing the status quo" It suggests that the environment did not improve easily due to existence.


"To the impression that they completely forgot the tacit knowledge that" move fast and break things "(quick action and destroy)", fart-powered cars said "exactly that. There was no time to deal with fatal problems and was always underperforming because everyone stopped quickly and the company did not offer a competitive and competitive offer to the technician.This is because engineers burned out That's why Tesla has driven everyone away. "


"People in charge of firmware have been swayed by the capabilities of Earon (mask CEO) for most of the time," he confessed that there was no time to correct serious problems due to correspondence with one-man executives.


"Since Tesla does not encrypt the firmware it is really easy to gather information from packet communications, just dumping the Tegra 3 used in Model S and Model X. Everyone believes Tesla's car It is far from the height of security it has. "


"The Tesla Group has little cooperation with each other, so the effort will increase" and the situation of the poorly workplace and the customers who frequently use the "supercharger" (fast charger) are blacklisted " We also disclose information such as.


fart-powered cars said, "Following the Roadster, the early Tesla of Model S, the early development of Model X was truly amazing, everyone was trying to prove that technology works, and indeed anyone can do it We have been doing innovative things we did not have. "I believe that" innovative Tesla "has modeled mass-sales model 3 and has transformed from starting to ship Model X.
