Which component is NOT typically included when learning about passenger vehicle anatomy?

When studying passenger vehicle anatomy, the primary focus tends to be on the physical and functional components of the vehicle itself. This includes understanding the engine size, which directly relates to the vehicle's performance and efficiency, as well as the chassis structure, which is essential for the vehicle's stability, handling, and safety. Safety features are also critical, as they pertain to the design and components that protect occupants during a crash.

On the other hand, vehicle history, while it may hold importance in assessing a vehicle's value, condition, and ownership, does not relate to the anatomy or mechanical design of the vehicle. Instead, it covers aspects like previous ownership, accidents, and maintenance records, which do not provide insight into the structural or functional elements that make up the vehicle itself. Thus, vehicle history stands apart from the core focus areas when learning about passenger vehicle anatomy.
