In "The Good Husband of Zebra Drive," the character Mr. J.L.B. Matekoni observes a connection between people's personalities and the cars they drive. He notes that some individuals seem unable to find joy or express kindness in any situation, which is mirrored in the types of vehicles they own. This correlation suggests that those who possess nicer cars are likely to be more pleasant drivers.

Matekoni reflects on how a person's choice in car, particularly its condition and type, can reveal much about their character. He believes that a person's vehicle can serve as a lens into their nature, indicating that those with poor-quality cars may often share similar negative traits. Thus, he sees the gearbox of a car as a metaphorical window into an individual's personality.
