Sometimes Google or car manufacturers will call AAOS "cars with Google built-in." Android Automotive is pretty rare out there in the world, but you'll see it on new Volvo/Polestar, Ford, and GM cars, mostly. AAOS has a car version of the Play Store, where you can download apps directly to your car, and it's this platform that Waze is arriving on. Even if there's an iPhone in your pocket, your car runs Android on the car's internal computer instead of something like Linux or QNX.

Cars have infotainment computers in them, and Android Automotive OS (AAOS) has the car run Android.

Automotive, the fully spelled-out version, is a full operating system instead of an app. Today's announcement is for Android Automotive, a different product from Android Auto. Waze has been on Android Auto since 2017.

This is Google's version of CarPlay-an app that runs on your phone but projects a special car interface to your vehicle's dashboard display, showing off Google Maps and compatible Android Auto apps on your phone.
