Android automotive doesn't come with software for battery management and functions like climate control, headlights, error notifications, and other driving functions. But it does provide the best toolchain, widget set and user interface framework for those functions. It also comes with support for multiple screens, multimedia, multiple languages, speech recognition, app stores, cameras, wifi hotspotting, OTA updates, modes for vehicles in motion, Bluetooth, pointing devices so you don't have to be all touch all the time, etc.

All that stuff adds up. As Volkswagen found out.

Green Hills supports running android in a VM so you can do all of the safety critical things like traction control, and ABS in a secure environment.
