# TechCrunch reports analysts’ concerns about Tesla’s Model 3 automation [Canonical reading](https://escapemeridian.com/readings/techcrunch-reports-analysts-concerns-about-tesla-s-model-3-36a3bb5b) TechCrunch published this report on March 28, 2018. It says Bernstein analysts Max Warburton and Toni Sacconaghi argued that Tesla was using too much automation in Model 3 final assembly, which they said was slowing the company’s ability to scale production. The report describes Tesla’s effort to automate final assembly tasks such as placing parts in cars, in addition to stamping, paint and welding. The analysts said the approach was expensive and could create problems in final assembly, welding and battery pack assembly. Their economic case was that automating some tasks might save little labor while requiring costly equipment and skilled engineers to manage and maintain robots. These figures are the analysts’ estimates, not independently established results in the article. The report leaves open why Tesla chose this approach. It does not establish whether the analysts’ concerns or cost estimates matched the performance of the production line.

It does not mention that TechCrunch relayed a Business Insider report, but this omission does not misattribute any claim. > Bernstein analysts Max Warburton and Toni Sacconaghi argue Elon Musk is overusing automation, Business Insider reports summary — pass: The title, summary and question match the article: the analysts argue that overautomating final assembly limits scaling, cite high capital costs and small labor savings, and say Tesla's rationale is unclear. Terms such as final assembly are explained in plain language. The question follows from the source's own open point. > This is where Tesla seems to be facing problems (as well as in welding & battery pack assembly). date — pass: The reading gives March 28, 2018, at day precision, matching originalPublished. The page was edited after publication, but the cited passages are plainly in the original article body. Later Most Popular items, such as Optimus production, are neither used nor relied on. There is no hindsight framing, and the question does not assert any outcome. The evidence kind is publisher-page, so no archive disclosure is needed. support — pass: Each claim is source-stated and has a matching verbatim excerpt. The reading frames the cost figures as the analysts' estimates and notes that the article provides no independent performance data. It does not overreach or infer unsupported benefits or costs. > So the net labour saving may be only $50 per unit. Yet putting the automation into the plant seems to involve an apparent capital cost that’s $4,000 higher per unit of capacity than for a normal plant. media — pass: No media is selected, and no verified media candidates were supplied, so leaving the media empty is appropriate. ## Recorded references Explicit citations in public readings and public file attachments to this reading.
