The App allows users to record video and audio while driving in the event of an accident or unexpected situation, with automatic recording triggered when connecting to a specific Bluetooth device and videos automatically deleted after three days unless saved. 

Once available, the feature can be launched through a new "Dashcam" shortcut in the "Be prepared" section of the home page. Here, you can begin recording manually or view your recent videos.

While Dashcam is recording, your phone is still fully usable, including for navigating with Google Maps. Alternatively, you can save power by locking your screen, and the recording will continue. More importantly, Google has built this feature to work without you needing to think much about it. When setting up, you can choose to have recordings begin automatically when you connect to a particular Bluetooth device (e.g., your car stereo or infotainment system) and end when you disconnect.

To conserve storage space, your recordings are automatically deleted after three days unless you save them. Additionally, the app says that the videos themselves are compressed, averaging "30 MB per minute," with a maximum recording length of 24 hours.

It's unclear if this feature will be available on other phones with Google's Personal Safety or exclusive to Pixel phones.
