Starting September 26, a fully autonomous, electric bus has served the Cheonggyecheon area of Seoul. These buses have eight seats, each with a USB port for charging devices, plus a large screen TV and a huge glass window that covers the entire roof. During the month of October, three buses are expected to operate in Cheonggyecheon, running every 15-20 minutes. At the moment the rate is free, since it is in its pilot operation.
