There's so many comments on the lines of "I would never buy a car without android auto/car play support". I 100% used to be on this camp, "A car without android auto, what am I, a caveman!?".

Anyway, separately to anything car related, I got fed up of some of google's treatment of android and switched to Murena's /e/os which is a de-googled spin of android. It doesn't support android auto, and that held me back from switching for ages.

Long story short, I don't miss android auto at all. Bluetooth is absolutely fine for playing media from my phone etc.

(my car does already have functionality like google maps built in though, so I might feel differently if it didn't)
