Tesla improving their manufacturing lines didn't almost cost them the company, it's what made them the raging success that they are today.
Saying that legacy auto knows how to manufacture in volume is doing a grave disservice to Tesla is who is showing legacy auto how bad their volume manufacturing and efficiency actually is. And these are the companies that laughed at Tesla because they had over 100 years of experience they thought was unassailable. In the four short years since the Model 3 ramp began, Tesla has shown them just how little that 100 years of experience was worth. That is the arrogance of legacy auto and it's also what caused them to become so fat and lazy that they can make hundreds of millions of cars over the last 20 years with barely any real profit to show for it. Products that are a terrible value and that threaten our climate. They have failed to do the number one thing that defines a good company: create value. They are value destroyers.
Legacy auto has become so fat and lazy that a small upstart named Tesla, a company smaller than a gnats eyelash relative to the majors, could waltz right in and show them how it's done. The entrenched automakers have been falling all over themselves trying to replicate what Tesla has done with EV's, right down to copying the large center screen that they were so critical of to begin with, and yet their cars
still don't measure favorably and they can't even hope to match Tesla on pricing or volumes without going bankrupt.
Yeah, legacy auto really knows how to manufacture in volume.
