Android auto-shutdown will take effect from android 12 onwards. Google claims that the Google Assistant system is better than Android Auto.
According to Google, the Google Assistant driving mode will be the default mobile driving experience. However, Google has no further details to share at this time.
In 2019, the Google Assistant driving mode was introduced and in late 2020, the system was launched. From then on, Google built most of the android auto to android 10 as a system-level feature as well as discontinuing previously downloadable apps.
Cars equipped with the auto android app will automatically be updated with the Google Assistant app. Meanwhile, for car users who are not equipped with Android Auto, the Google Assistant system is not compatible.
