I’m sure there are some use cases where you absolutely need a screen. Phone calls and maps directions though are actually very nice, and I would argue superior, using just a headset instead of the screen. The usage of mobile screens differs across the world as well. In my experience, in south and east asia people are glued to their screens much more than in other parts of the world (probably because the rest of the world still catches up). So such a rule might not seem as necessary in other parts of the world, yet.
