Tesla better have plans to add Apple CarPlay and Android Auto functionality. Just add both -- although the Windows Phone contingent won't be happy (but Microsoft doesn't have this type of functionally, at least yet). If Volvo, Honda and Hyundai can support both on cars coming out this year, you can beat them to it by rolling it out to all existing Model S!

This doesn't actually put the OS in the car... Instead, its basically a type of remote display that lets you view output from the phone on the car, and provide input back to the phone for controls. The aspect ratio can be different than the phone -- and it would most likely be a 1/2 screen app on a Tesla implementation. I'm sure there will be some minimum hardware specs, but the Tesla's Nvidia-powered center screen should more than meet those... The Apple CarPlay implementations shown a few months ago all have different hardware and different input methods -- Volvo's being capacitative touch, Ferrari's with resistive touch, and Mercede's with the knob based control and no touch...
