You do know we have a lot of hard drive companies here right? If the valley can R&D hard drive and precision semiconductor equipment going into clean room (and robotic surgery), car's tolerance and material expansion rates is not that hard.I was not only referring to Googles and Facebooks of the silicon valley. R&D, studio offices even chip manufacturing is not the same as automotive manufacturing where many complex systems need to be integrated into one coherent product. Where you have to deal with tolerances, different material expansion rates, assembly processes etc.
Why do you think Tesla struggled so much? It was because Musk didn't understand these challenges at all being from the computer/programming background.
The problem is more of a labor cost here, and people don't like to work for a company that won't grow its stock value much, and management that doesn't reward overtime work (i.e. 55 hours a week) with big bonus and promotion (i.e. lots of stocks).
Elon just doesn't care about building durable boring stuff when the cool stuff is always 18 months away, that's what you get in Tesla: cool stuff that's a few years ahead of competition in design, but don't expect boring durable reliable appliances like Toyota. (I love boring durable reliable appliances)
