What? Most of these scooter riders are trying to deliver something: they aren't the usual method of transport for most people in Seoul. Seoul also has extensive road system, including two freeways cutting through it from end to end (one on either side of the Han River), and one highway that goes around the city in a full circle. They are pretty heavily used. A lot of people still take subways because it's the most convenient for many destinations. Without subways, these highways will grind to a traffic hell.
