A long novella that follows a highway patrol squad on duty in a future where the highways a several miles wide and the cars are going several hundred miles per hour. There is not much of a story. The squad do regular things like handling accidents, bank robbers and even a baby birth.
The writing is competent but I fail to see any point to this story. It doesn’t really need to be science fiction. It is basically just faster cars and larger highways as a background setting for a rather mundane description of the working lives of this highway patrol.
I suppose the appeal is that it shows appreciation for the everyday working heroes and such professions are still needed in the future, but there is not much appeal to this story today.
