What Do You Think?

As John is driving to work, the Narrator notes that there's not much traffic at this time of the day. (In fact, John and the Woman's cars are the only ones on the street, and no one is visible on the street or in the neighborhood yards.) Shortly after the crash, as Joe rushes to the accident site, the Narrator refers to "other, nearer Samaritans" who have arrived on the scene (as well as another car) before John. At least a half dozen people, all fully dressed in business clothes, have arrived from the deserted street and yards and gotten to the scene before John, and many more arrive within seconds later.
