The car analogy is a common technique used by engineering textbooks to ease the understanding of abstract concepts. ==Uses of car analogies== The efficiency of car analogies reside on their capacity to explain difficult concepts (usually due to their high abstraction level) on more mundane terms with which the target audience is comfortable, and with which many also have a special interest. Due to that, car analogies appear more often on works related to applied sciences and technology. In order to work, car analogies translate agents of action as the car driver, the seller, or police officers; likewise, elements of a system are referred as car pieces, such as wheels, motor, or ignition keys. Resources tend to appear as gas, speed, or as the money that can be spent on better accessories/vehicles. For example, in the paragraph:
Current (resource) is depicted as the car's speed, while the role of the brakes is performed by the Zener diodes (element of the system). Car analogies are also typically used to explain the quality differences between two similar tools or hardware pieces; in that case, the best one is usually described as a mid-engined Italian supercar or a high-end luxury vehicle. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「car analogy」の詳細全文を読む スポンサード リンク
