They use the North Korean Won.
North Korea use North Korean won. South Korea use South Korean won.
North and South Korea do.
The currency in South Korea is South Korean Won (KRW).
The people of South Korea identify themselves as Koreans or ROK (Republic of Korea). In common-parlance they will use the term "South Korean", but only to clarify that they are not from North Korea, not as a general identifier. The Korean term for "Korean person" is Hangkuk-een (한국인).
People use cars so that they do not have to walk. So they can get there faster.
The odometer being Korean has nothing to do with anything. Odometers use the required distance measurement of the country of sale. So, for example, all Korean cars (and other cars) sold in the US will have a display in miles, since that is the US requirement. However, all US cars (and other cars) sold in Korea will have a display in kilometers since Korea uses kilometers.
The people of South Korea identify themselves as Koreans or ROK (Republic of Korea). In common-parlance they will use the term "South Korean", but only to clarify that they are not from North Korea, not as a general identifier. The Korean term for "Korean person" is Hangkuk-een (한국인).
Most people that name their cars use a females name.
North Korea is not the only country that uses propaganda. Every country in the world does; it is just much harder to recognize propaganda in your own country. We notice North Korean propaganda because it is more ridiculous and overstated than most countries' propaganda. The reason North Korea uses propaganda is to create a society less willing to revolt against the North Korean government. Currently, the North Korean government starves many of its own people, lacks any serious internet capabilities, requires all of its citizens to belong to the Juche religion (worshiping the previous leaders of North Korea like gods), and place hundreds of thousands of prisoners in camps. Any sensible group of people under those conditions would at least consider rebellion. However, the North Korean government has carefully calibrated the propaganda machine in its own country to "inform people" that the world outside of North Korea is significantly worse and the US, South Korea, and Japan are all conspiring to hurt the North Korean people. In this way, the tyrannical North Korean government looks like a hero as opposed to the monstrous villain that it is.
