Purpose of 'The Pedestrian

Ray Bradbury may have written this story thinking that in the future, life would be very simple. This meaning that there just won’t be much to do as he explains in the book with his characters. In the book there is one man though, who acts like people, “From the past” did, and he is stopped by a “cop”. The man is stopped for walking in the street and is called regressive. So Ray Bradbury might have written the story, thinking that in the future, people’s lifestyles may change, tremendously, but in reality they haven’t changed much from before. He also may have written this book on order to try and keep people’s lifestyles the way that they are now or before. Whatever the reason, nothing has really changed and I don’t really expect a lot more change in the future
