According to a report by Markets Insider, a Wall Street analyst warned on Tuesday that the very same tented assembly line that helped Tesla reach its Model 3 production goal on Sunday could also be working against it. An analyst at Evercore ISI, George Galliers, said in a note to clients on Tuesday that Tesla's extra assembly line, constructed in a tent next to its main Fremont, California factory, could be a long-term risk to the company's reputation.
