bumper-sniffing

To come to a sudden, dead stop in the middle of a busy pavement to check your phone, consult a map, or simply contemplate existence, creating a human obstacle for everyone behind you.

Greeting a delivery driver using GPS timing rather than the sound of the doorbell.

The deeply selfish, laser-focused staring at a blank mobile screen utilized by a seated passenger when an elderly person boards the train.
