Very often, my L535DS shows the below screenshot:
I can confirm that it doesn't have any such sensors. And it shows up the same screen most of the time when I'm watching some video. Is it a bug or something? As it becomes very annoying when I saw the screen two to three times in a 18 minutes video😒.
Driving Mode automatically starts when your associated bluetooth device is connected to your device. As Microsoft states in this document
Once you set up a device, driving mode will automatically start whenever your phone connects to the device
This is the bluetooth device you selected while configuring driving mode for the first time.
