There appears to be a new feature in the Pixel 2 and the Pixel 2 XL which Google didn’t talk about during the announcement. A description hidden under something called Pixel Ambient Services indicates that the phones will be enter to automatically enter Do Not Disturb mode when the user enters a vehicle.
Android Police first reported the unusual option and posted a screenshot of the Pixel Ambient Services app from the Google Play Store. The image clearly shows a notice referring to feature listed underneath a toggle for driving mode.
From what we can gather, it refers to a Do Not Disturb mode that will active while you are in a moving vehicle. A condition that the description states will be determined by the device motion and Bluetooth connections. Which most probably means that you have to connect your phone to your car via Bluetooth in order for this feature to work.
However, there is no description mentioning how does the feature determine whether you are the driver or the passenger of the vehicle, we’re guessing that passengers will most likely have to turn off the feature with the toggle. Although, we admit that most people will not be connecting their Bluetooth to cars that don’t belong to them.
The feature however will most likely be a Google Pixel exclusive feature as the app shows the always-on music scanning feature called: Now Playing as well. More details on the Do Not Disturb feature will only be available after Google starts shipping the Pixel 2 and Pixel 2 XL.
