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: https://youtu.be/YAtLTLiqNwg?t=1024 https://youtu.be/YAtLTLiqNwg?t=1024
