The study of how cars are designed to look sexy is an interesting one because it involves many factors such as body proportions, color schemes, lighting, and overall visual appeal. While these aspects are important for all types of cars, there may be some that cater more specifically to certain types of psychological drives.

Sports cars tend to have very low and wide bodies with aggressive angles which can create a feeling of power and control for both the driver and spectator alike. On the other hand, luxury sedans often feature sleeker designs with elegant curves that give them a smooth appearance. This type of design can convey wealth and sophistication while also being pleasing to the eye. It's possible that some people may even find themselves aroused by these car styles due to the way they make them feel on a subconscious level.

It's also worth mentioning that different cultures have various perceptions when it comes to what makes a vehicle attractive based on their cultural values and beliefs. In Japan, for instance, high-performance vehicles are seen as status symbols whereas in America, SUVs are typically associated with family-friendliness.

Colors play a huge role in how appealing a car appears to others; red tends to signify danger while black conveys class and luxury.

It's unclear exactly why cars evoke sexual feelings within us but there could be several explanations. Perhaps our brains associate certain shapes or colors with things we find attractive in real life like human body parts or animals; after all, our minds do process visual information similar to how they would perceive nature around us. Alternatively, automobiles could trigger primal instincts related to procreation because they represent objects capable of transporting people from one place to another - something crucial for survival during prehistoric times before modern means of travel existed. Whatever the reason may be, these factors combined with individual psychology create complex interactions between person and object that are fascinating to explore further through research studies!
