Definitely! I'd love to see a big Tesla plant driving down 101.
It does worry me that if he builds a large portion in house, does it then scale as well as say a Toyota? Is supply chain management somewhere in his background?
I think supply chain management is less of a problem now that a single CnC machine can make a wide range of parts. The goal of any supply chain should be balancing the number of suppliers with the overhead costs. And I think that's been shifting to fewer suppliers for a while now.
