How does the author use foreshadowing in Driver's Ed?

Remy's minor driving mistake of going over the median foreshadows the big mistake that she will later make. How Mr. Fielding handles Remy's driving mistake also foreshadows his later actions in the novel. When Remy drives over the median, she keeps going forward with a bad decision, because she can't think of a better plan. Mr. Fielding gives her no assistance at the time, but afterward blames her for doing the wrong thing.
