| ## 9.14\. Automotive Vehicle System Isolation | |
| Android Automotive devices are expected to exchange data with critical vehicle | |
| subsystems by using the [vehicle HAL](http://source.android.com/devices/automotive.html) | |
| to send and receive messages over vehicle networks such as CAN bus. | |
| The data exchange can be secured by implementing security features below the | |
| Android framework layers to prevent malicious or unintentional interaction with | |
| these subsystems. |
