A car can be seen as an extension of the human body, especially when it comes to its design and performance characteristics. The shape and structure of a car's exterior are often compared to that of the human form, while the engine represents the energy and power behind driving. This analogy has led to the concept of "car erotics", which is the study of how cars can be perceived as sexual objects and how they can arouse sexual feelings in people. One such example of car erotics is the Mercedes 190 SL, a classic convertible that was produced from 1954 to 1963. The 190 SL featured heated seats as an optional extra, which were considered highly unusual for the time and were marketed as a luxury feature. These heated seats could be turned up to reach very high temperatures, making them an appealing option for colder climates.

Some people have also suggested that these seats may embody phallic or feminine symbolisms, depending on their interpretation.

The heat generated by the seats could be seen as representing masculinity and potency, while their rounded shape and smooth curves could be interpreted as feminine. In terms of psychosexuality, this could mean that the heated seats in the 190 SL represent both the desire for closeness and intimacy with another person, as well as the fear of rejection or loss of control. It is not surprising then that many people associate the 190 SL with romantic or sexual experiences, whether real or imagined.

Some car enthusiasts even suggest that the heated seats in the 190 SL could be used as part of BDSM play, where one partner sits on the seat while the other controls the temperature. This would create a dynamic between dominance and submission, where the driver has power over the passenger's comfort level. Other potential uses include using the heated seats to create an erotic atmosphere during foreplay or sex itself, either alone or with a partner. The intensity of the heat can be controlled, creating a range of sensations from mild warmth to intense burning. The design of the seats themselves could also be incorporated into role-playing games, where they are seen as a symbol of female genitalia. All of these scenarios highlight the connection between cars and sexuality, which is often underestimated but undeniable.
