I thought Face ID was simply for unlocking the device and for security. I was pleasantly surprised when I was driving home with my new XR mounted on my dash using GPS, and my text notifications turned into previews when I looked at my phone. This is especially useful when doing Lyft or driving with friends or family in the car. I think Apple should have promoted or marketed the attention awareness features more. Despite how much people may or may not use them. It should have been the X’s “killer app”.
