Probably the most famous example of foreshadowing in the novel is the confused car accident at the end of one of Gatsby's parties in which people mistake who is driving:
“You don’t understand,” explained the criminal. “I wasn’t driving. There’s another man in the car.”
This foreshadows the car accident near the end of the novel when Daisy runs over Myrtle, but people such as Wilson believe that Gatsby was driving the car.
Another careless driving incident foreshadows both the final accident and the end of Jordan and Nick's relationship. Jordan drives so close to some workmen one day that she flicks the button off a coat of one, suggesting that she almost ran him over. Jordan and Nick have the following conversation:
“You’re a rotten driver,” I protested. “Either you ought to be more careful, or you oughtn’t to drive at all.”
“I am careful.”
“No, you’re not.”
“Well, other people are,” she said lightly. ...
“Suppose you met somebody just as careless as yourself.”
“I hope I never will,” she answered. “I hate careless people. That’s why I like you.”
As she is breaking up with him after the events of the accident with Myrtle, Jordan says:
I met another bad driver, didn’t I? I mean it was careless of me to make such a wrong guess. I thought you were rather an honest, straightforward person. I thought it was your secret pride.
Chapter 1 is also an example of foreshadowing. In chapter 7, the same cast of characters, with the addition of Gatsby, will assemble in the same room at the Buchanan's house with the “wine-colored” rug. As in chapter 1, the tension level will be high, and as in chapter 1, an extramarital love affair by one of the Buchanans will drive the tension.
Hints in chapter 1 also foreshadow that Daisy will never leave Tom. Nick is surprised that she tolerates Tom's affair without fleeing:
It seemed to me that the thing for Daisy to do was to rush out of the house, child in arms—but apparently there were no such intentions in her head.
Nick also feels as if he has been “played” by her and
as if she had asserted her membership in a rather distinguished secret society to which she and Tom belonged.
This foreshadows Nick seeing Tom and Daisy after the car accident “conspiring together” over cold chicken.
