Apple made some public comment today referencing their own Apple Car ambitions, saying something about how, "cars are the ultimate mobile device"
(something like that, I'm paraquoting.)
Anyway, it's debatable that a platform you may spend a hour or two a day with being the "ultimate mobile device" (whereas my phone moves around with me 24/7/365.25)
Also, what is the likelihood that Apple can out-Tesla Mr. Musk? Isn't it more likely they want to acquire Mr. Musk and his Tesla enterprise, and all the PR around the prospects of an Apple Car are just opening that door?
