It isn't just the touch aspect, but also the "ruin your night vision" aspect. Most pedestrians don't carry lights around, or even wear light-colored clothing at night.
All screens (that aren't OLED ones, which aren't generally suitable for cars due to their shorter lifespan) still glow when displaying black.
So it's still a glowing thing in your field of vision. Of course, you're already going to be flash-blinded by retards leaving their LED high-beams on as they pass you, so maybe none of this matters.
