Several factors contributed to his eventual focus on car manufacturing:
* Existing technology and limitations: Ford was initially involved with improving engines and saw the limitations of existing automobiles, which were expensive, unreliable, and difficult to maintain. He saw an opportunity to create a better, more accessible product.
* Vision of mass production: Ford was a visionary who recognized the potential of mass production techniques, which he perfected through the moving assembly line. This allowed him to drastically reduce the cost of manufacturing automobiles, making them accessible to a broader market.
* Personal ambition and drive: Ford was ambitious and determined to succeed. He saw the automobile as a means of achieving his goals, both financially and in terms of revolutionizing transportation.
So, while it wasn't a singular decision to *make* cars, it was a confluence of factors—his engineering background, his understanding of mass production, and his ambition—that led him to dedicate his life to creating a reliable and affordable automobile and revolutionizing the industry in the process.
