I lived in korea for a year (seoul, army) and my husband is from indonesia. I can't imagine biking the streets of seoul!!! crazy traffic.
They used to tell us when crossing streets- if you don't make eye contact with the driver, you have right of way, if you make eye contact, they have right of way. It was hard to tell, driving, who had right of way anyhow. But there were many bicycles, heavily loaded, on the streets all the time.
