It would be cool to mirror the phone screen on the Tesla touchscreen display. Even better would be to send gesture input back to the phone from the main display back to the phone to control apps.
Technically it is possible using Bluetooth and is it can be done with a phone app.
Moderator: Due to regulations and legal liability, it is doubtful this will ever happen for any vehicles. Regulations (in the USA) do not allow video to be viewable by the driver while driving. With total access to all apps, many (most?) will offer a huge distraction while driving (games anyone?). Tesla might implement CarPlay and/or Android Auto that has a separate validated app that is functionally limited for cars, but that’s a different feature than mirroring.

There was talk from Tesla years ago about a mirroring option, but it appears to have been abandoned. Perhaps mirroring creates regulatory, security issues, or technical issues.
