This might be an unpopular opinion, but I'll take a car infotainment system that doesn't need CarPlay/AndroidAuto to be usable (and lacks it) over one that requires a phone attached via CarPlay/AndroidAuto to be usable.

I use Android Auto on rental cars all the time.

My daily driver is a Tesla (Model S /w MCU v2) that doesn't have it. And doesn't need it to provide a usable experience.

If the software has the same library as your phone, then I could why you see it as on par.

Android Automotive has a much smaller library than Android Auto, so the selection for audio apps, such as podcasts and music, are much more limited. The options for map software is smaller too. Also Android Automotive doesn't necessarily use your phone's existing internet connection. Depending on the maker, you have to subscribe to a separate data plan.

I've only rented Teslas but I can see how most people would consider CP/AA to be unnecessary given the quality of their integrated software. But for me, the two things Tesla can't do (and CP/AA can) is

1. Waze;

2. My preferred third-party podcasting app.
