The psychological study of how cars affect human sexuality is called automophilia. It involves an individual's sexual attraction to vehicles or their physical parts. Some people find themselves aroused when they drive a vehicle fast, feel its smooth leather seats, smell the gasoline, listen to the engine noise, or admire its shape. Others fantasize about being inside a car with someone who drives them to orgasm. Researchers have found that some people get turned on when driving because it allows them to escape from reality and live out fantasies. They may also associate certain brands of cars with specific feelings or memories related to sex.

Porsche can be associated with power, BMW with luxury, Mercedes-Benz with status, Ferrari with speed, etc.

There are those who prefer vintage or classic cars for erotic purposes. They might see these as symbols of tradition, masculinity, or nostalgia. Sexual fetishes like "car play" involve roleplaying scenarios involving cars in which individuals take part in various activities such as kissing, touching, masturbation, etc.

There are different ways to define automophilia. It could refer to the act of having intercourse while inside a moving car or simply watching others engage in sexual activity while riding in one. It could mean feeling arousal from the sight, sound, or touch of a vehicle. People may enjoy wearing sexy clothing or lingerie while sitting behind the wheel. The term also includes other types of pleasure derived from machines, including robotics or technology. This phenomenon has been studied in psychology since the 1970s and is considered a form of paraphilia. Some theories suggest that it stems from childhood experiences where children learn to associate cars with freedom, excitement, control, adventure, or dominance. Automophiles can experience confusion about their identity if they feel embarrassed about their attraction.

Automophilia is an interesting field of study that investigates how people's interactions with cars influence their sexuality. It suggests that our emotions and desires can be strongly linked to objects outside ourselves.
