I have a 2019 Subaru Outback. I also use GrapheneOS on a Pixel 3A. I have noticed that, when my phone is plugged in and I have location services enabled (for navigation), when I'm NOT using navigation, the icon in the top bar indicating location services being used pings once every 30 seconds. I'm sure onboard cell modems can be used to triangulate well enough, but just knowing that my car likes to hitch a ride on my phone's sensors has creeped me out forever. I'll definitely be looking for an old beater car as my second when the time comes.
