I saw these all over Seoul and now I am seeing one here also. At first I thought it was for the mail delivery, it is motorized. But in Seoul I saw one which I think was delivering soy milk to peoples homes in those old falling down suburbs with steep streets. Now I am seeing this one which is just an iced coffee van. So there you go, in Korea everything gets delivered in a little robotic motorized cart thing.
