Only Uber doesn't have a self-driving program anymore, and Tesla can only be used in their own ride-share network.I'm sure someone did.
But it's different, you're buying a device you own and use, and you get the Apple system, and the device brand/OS matters. That being said, I think Apple will have trouble justifying their price premium to the next generation who grew up on Chromebooks. iPads are nice, but if all you're doing is using Gmail and google Chrome... why pay the Apple premium.
With self driving uber, you're buying transport, the brand stamped on the wheels doesn't matter.
