Now, Google is cribbing that handy feature for the new and .
The new Pixel Ambient Services app, which will come preinstalled on Google's latest flagships, includes the feature -- though it's off by default. You'll need to enable it in the Do Not Disturb settings before it starts checking to see if you're driving.
The app says it uses a combination of Bluetooth and device motion to tell, presumably by checking whether your phone's accelerometers are bouncing around and if your phone's Bluetooth radio sees opportunities to connect to Bluetooth-enabled cars.
Note the app is exclusive to the Pixel 2 and Pixel 2 XL for now -- you can't install it on earlier Pixel devices (we checked) and it's not part of a broader Android release that phonemakers can add to their new devices, either.
But don't rule that out: It's CNET's understanding that Google's collecting feedback before deciding whether to roll out the feature more broadly. Like, another feature that'll be exclusive to Pixel at launch, it may arrive on other devices soon.
The feature was originally reported by Android Police.
