Not OP. But I'll give my feedback on why I stopped using android auto.

Let me preface this with most everything in the app is fine. Navigating around the interface is maybe a bit janky but not something that I couldn't get used to.

The main thing that pushed me away from it is the constant crashing (crash every 1-3 minutes). I understand it to be a somewhat rare issue. But through my research I have not found any way to consistently solve the issue despite finding threads that were posted years ago.

The closest I had come to a solution was to clear some app caches (like Google maps) and that would fix it for the next day or two. But it would always eventually go back to constant crashing. It just became too frustrating to deal with.
