There is not a phone on the market that will project an interface over Bluetooth to a display in the car. What curve are they behind exactly?

Do you really think it's mirroring the phone's display onto the car's screen? That would be pointless, as you don't want dozens of irrelevant app icons cluttering your car's display. You want the basic controls that are useful in a car, with large targets that can be hit with a glance and later with muscle memory.

If you really think they are just mirroring the display, then you didn't even look at the linked Apple page.

My guess is that the iOS SDK has been expanded to allow for a second screen that is output over lightning. So no, it's not mirroring the phone screen, but displaying another screen powered by the phone. This would seem to fit with it being iPhone5 and above only as lightning is designed to have these sorts of custom digital output.

Correct. At a minimum, it's a secondary display. But it's also deep integration into both ends over the Lightning cable (hence the iPhone 5 requirement).

Yes, this is the case. External screen support was added a few years ago.

That makes a lot of sense, thank you.
