Provincial maps are relatively good. This map isn t available in bookstores. On my first visit to Korea I wrote, in English, the names of major places that were on my route onto the Korean provincial maps. Korean Roads and Their Safety Traffic flows on the right, and roads are wide. There's little reason for cars to push you off the road.
Taxis ignore everything when they spot a customer.
In their rush, they pull over to the right without first scanning the road. Buses perform the same careless driving maneuver, careening toward a bus stop when they see people waiting. Always be extra alert whenever you see a bus in any situation. Bus drivers do not obey any traffic rules. Crossroads, in general, are spacious.
