Flink's Three Stages of American Automobile Consciousness fully expresses the progress of the entire automobile industry. From the first Model T to automatic production, it gives me an intuitive sense of the history of the automobile as a whole. On the other hand, Kline and Pinch focus more on a certain group of people - farmers or people living in rural areas - who they use as an entry point to talk about the automobile, only with the transition of roles and duties between men and women.
