This might be interesting to check out the next time I am in Seoul:
Self-driving transit buses are expanding their presence in Seoul, as the city introduced, Wednesday, a new route in Yeouido, western Seoul. It is the city’s fifth autonomous bus service route.
Korea Times
At 12 p.m., a Hyundai Solati, a diesel minibus accommodating up to 13 people, took to the road around the National Assembly and it drove a round trip of 3.1 kilometers that featured six stops around the parliament.
Two autonomous buses run every 30 minutes from 10 a.m. to 4 p.m. from Monday to Friday, but they do not operate on statutory holidays and weekends.
Those who want to ride the bus need a smartphone app called TAP!, where users can pre-book a ride by setting their departure and destination.
