A man, Leonard Mead, goes for long walks every evening by himself. The year is 2053, and Mr. Mead is the only pedestrian near his home.
On this particular evening, a police car stops him and orders him to put his hands up.
He answers a series of questions about his life and family, and his answers are unsatisfactory to the police. This car is the only remaining police car in the area.
They order him to enter the car despite his protests, and as he approaches he realizes there is no driver at all - the car is automated.
The car informs him that he is being taken to a psychiatric center because of his regressive tendencies.
His behavior is not acceptable in society - no one walks anymore and it is queer that he continues to do so as his primary hobby. Mr. Mead's behavior is completely atypical of the society in which he lives.
