Apple, like Tesla, share the same valley space in Southern San Fran. Elon Musk has eluded to this as well, as a reality in the very near future. To be perfectly frank, it's a natural fit for these two to be on the same vector and with the OS developer cycles with Apple after iterations with Darwin / Unix - which oh ya BTW runs some of the NASA space junk we have floating around - is the natural fit for Tesla. Maybe .. just maybe we see the Apple OS running Tesla cars in this fashion. I mean, it's almost obvious that these two are dating. I think the rest of the world maybe ignores it, but to me .. it's damn near obvious what the collaboration is, possibly already.
