> If anything becomes possible, easier, faster, etc. to do on another device then you arrive at n + 1 screens That's kind of the whole point of Android Auto/Carplay. New software feature out there? It's there. Things too slow for the features you want? New phone, faster CPU/GPU, new network connectivity, etc. Even though my Hyundai is >5 years old it's running apps that were last updated yesterday. It's had a few UI changes, mostly for the better. It didn't take a new screen.
