Final answer:
Gatsby objects to letting Tom drive his car as it signifies a transfer of power and represents Gatsby's wealth and status, which he is reluctant to relinquish.
Step-by-step explanation:
In F. Scott Fitzgerald's novel The Great Gatsby, Gatsby objects to letting Tom drive his car because it represents a swap of power and control. Although the specific scene where Gatsby objects to Tom driving his car isn't provided in the text excerpts, within the overall context of the novel, Gatsby's car signifies his wealth and status. Allowing Tom to drive his car, therefore, could be seen as Gatsby relinquishing his status and giving Tom control over something that defines him. It is an important moment that reflects the complex social dynamics between characters, highlighting Gatsby's resistance to Tom's dominance in both the social and personal spheres, as Tom is married to Daisy, whom Gatsby loves.
