Also the reverse -- CarPlay knows where I have been, where I have searched, locations people have texted to me, locations in my calendar, etc. It's nice to not have to type in the address every time I want to go somewhere new.
Not quite as seamless, but for anything like that where you’re headed to a destination, you can always send the location to these various UIs. Tesla and Rivian support sending addresses to their cars via their apps (through the share functionality, so it’s basically 2 clicks).
For the calendar point, Tesla actually offers calendar integration and automatic navigation (if you enable it) to events that have locations near your current time. I don’t use it since my calendar isn’t heavily populated, but I could see that being super useful for certain people.
