I briefly tried to find a source and could not, but I seem to remember Musk making some statement re. the Model X that supplier delays were an issue for Tesla and he desired to be able to manufacture more components in-house.<p>While the chips wouldn't be moved in-house, I wonder if the fact that this chip is related to the self-driving technology is just a coincidence: perhaps this is to switch to another vendor that might fit better into the Tesla supply chain.
