How do science fiction and the story "The Pedestrian" relate to each other?
Ray Bradbury's story "The Pedestrian," published in 1951 shortly after the invention of television, relates to science fiction because it is set in 2053 A.D.; there are more shows on TV than in 1951, there is also a technologically driven motor police vehicle that also "talks," and society is markedly different from that of 1951.
Other things are very different from 1951, also. In this year 2053, there is only one police car in the community where Leonard Mead walks; however, this police car is able to cover the community because there are no longer people on the streets. Mead wears sneakers when he walks so that the dogs will not be startled by the rare sound of footsteps on the pavement and begin to bark, thus alerting the police.
The street was silent and long and empty, with only his shadow moving like the shadow of a hawk in mid-country.
When Leonard Mead is stopped by the remotely driven police vehicle, he is asked what his profession is. When he replies, "I guess you'd call me a writer," the police car retorts, "No profession." This judgment is made because since there no longer are readers, Mead is not producing consumable goods that are economically viable.
