Answer

From the viewpoint of the driver, a car is one single object. It can be operated using gears, indicators, accelerator, brake, etc. The driver doesn't need to know or understand the internal mechanisms of how these components actually work. From the viewpoint of the mechanic, it is important for him to understand how the internal mechanisms like gears, indicators, accelerator, brake, etc. actually work so that they can identify and fix issues with the cars. For a mechanic, each car part is a single object.
