I finally figured out what bugs me so much about people walking while looking at their phone. Without phones, when people approach each other in a hallway or on the street, there's a lot of nonvocal communication happening. You don't even have to make eye contact to decide how everyone is going to maneuver around each other. Everyone is generally looking at a point far ahead and walking in a straight line towards it. Now enter smartphones. This entire communication is simply gone. People on phones only see about a couple meters in front of them. They constantly shift the direction they are walking. It's impossible to predict where they will go. If you're walking towards them, this creates a small spike of anxiety in your lizard brain because it's trying to communicate with them and the lines are down.
