So Park Chung-hee didn't plan the Gyeongbu Expressway after seeing the German Autobahn?

The plan to construct the Gyeongbu Expressway was already part of the 1962 economic development plan for national modernization.
However, the country lacked funds, and at that exact time, West Germany requested the large-scale dispatch of miners and nurses at a national level (it is said that miners and nurses had been moving to West Germany even before then).
Subsequently, in December 1964, Park Chung-hee visited West Germany and held a summit with West German Chancellor Erhard.
Erhard was known as the key figure behind the so-called "Miracle on the Rhine."
During the summit, Park Chung-hee explained Korea's current situation and economic development plans, and Erhard spent a long time explaining the importance of building basic infrastructure such as roads, ports, and steel mills (you could call it a lecture rather than an explanation).
It is said that Park Chung-hee was deeply impressed by this. Upon seeing the seemingly endless Autobahn during his visit to West Germany, he decided that the construction plan for the Gyeongbu Expressway should be moved forward.
He once again emphasized the need for loans to Erhard and, using the loan agreement signed in 1961 as a basis, brought in 75 million Marks (approximately 55 billion KRW) in the form of long-term loans that year.
The Gyeongbu Expressway was constructed and the plan for POSCO was established using these West German loans and the foreign currency earned by the miners and nurses.
There are many controversies, but the more you look at him, the more mysterious a figure he is.
With his forward-looking mindset and drive, he could have built the top two companies in South Korea even if he had pursued business instead of politics.
