That's a thing in a lot of newer cars. Contains various sensors like the "is the windshield wet" sensor, daylight sensor, and so on. I guess from googling it seems like the main thing is a collision detection (prevention?) sensor? Maybe LIDAR or something?
Kim went to international school in Switzerland, so he would know English and German. I’m not sure if North Korea teaches Russian like Cuba did though.
Putin obviously knows English and German from his posting in Germany during his KGB days.
In the video that was published by Russian media, it shows Kim and Putin taking turns driving the car. Feels like a dudes rock moment. The car is an Aurus Senat.
