A person who is interested in cars may have a deep fascination with their physical attributes such as the shape, size, sound, color, speed, power, efficiency, handling, design, history, and performance. This can lead them to develop an emotional attachment that goes beyond mere functionality. They may even become aroused when driving their car or experiencing it from afar. Eroticism is not limited to humans alone, but animals too feel passionate about mating. Many people find themselves drawn towards cars for various reasons like their beauty, comfort, or prestige, which is known as automotive fetishism. The act of coasting silently down a hill evoke erotic surrender to motion and environmental stimuli. It allows the driver to experience the car's movement without having to control it and thus creates a sense of passivity and relaxation. Some studies suggest that this can be an effective way of relieving stress and tension.

The term "automotive" refers to anything related to cars or vehicles, including engines, parts, accessories, and services. Automobile sex is also referred to as autoeroticism, where one derives pleasure from touching or looking at their car or other objects associated with it. Cars are often used in sexual fantasies and role-playing games due to their unique features and capabilities.

A woman might pretend she has been kidnapped by two masked men and locked up in her car trunk while being driven around town. A man might imagine his car as a person and talk to it like he would a lover. There are many different ways people use cars in their sexual lives, such as parking lot rendezvous, cruising, drag racing, and even street races.

Fetishes are defined as strong desires or obsessions with something specific, usually nonsexual. They may involve certain objects, body parts, activities, or behaviors. In relation to cars, some people have a fetish for certain models, brands, colors, types of engines, or modifications. Others may prefer old classics over new ones, or vice versa. This could manifest itself through collecting them, customizing them, or restoring them. Fetishists may also wear clothing related to cars or car parts like racing suits or helmets. Automobiles can create feelings of arousal and excitement, but they should be treated with respect and caution since they require maintenance and safety measures.
