The Pedestrian
Ray Bradbury
 In this story we encounter Leonard Mead, a citizen of a television-centered world in 2053. In the city, roads have fallen into decay and people only leave their homes during the day, staying home at night to watch TV. It is revealed that Mead enjoys walking through the city during the night, something which no one else does. On one of his usual walks he encounters a robotic police car. It is the only police unit in a city of three million, since the purpose of law enforcement has disappeared with everyone watching TV at night. The police car struggles to understand why Mr. Mead would be out walking for no reason and decides to take him to the Psychiatric Center for Research on Regressive Tendencies.
