I hope, if they don’t incorporate CarPlay, that they make the ui easier to parse while driving. Larger cards during navigation, better timed audio prompts like in apple maps. Not having to reach across the entire screen to access your Apple Music library etc. I’m a recent convert to Apple Maps, 95% of the time it’s as good as Waze (at least near me) it’s just easy on the eyes and very clear what the next turn will be.
I‘ve had the Tesla nav take me to a supercharger in a really circuitous way. Felt like I was using my old Prius’s on board nav from 2007.
