First of all, if this has been discussed before, my apologies. This thought crossed my mind today as I was looking at all of the Signature deliveries that happened in the last 48 hours. Will Tesla start using the train infrastructure that is built into the factory once they are producing 400 cars a week? If not, what production rate/week would it start making sense to use the trains? The reason I'm wondering is it seems somewhat inefficient to be driving semis cross country when you will need to bring 200-300 cars to the east coast in a single week. In case anyone is wondering why I'm curious it's because I'm always intrigued by the economies of scale and how businesses make decisions. Thanks in advance for your thoughts!
