Except that Tesla is the keyboard. They are never going to duplicate every app on iOS and Android, so they should focus on connecting those OSes to their screens, speakers, and physical controls (like volume) rather than build something just for their hardware.
100% agree. One of the most consistent irritations with my Tesla is the inability to use CarPlay. The only thing that Tesla does better is navigation. And even then, it's only because built-in knowledge about superchargers and battery SOC. This information can be made available via CarPlay.
