I came back from a week driving around Seoul and was blasting my horn at everything that moved. Okinawan's are so polite they just waved and gave way. (I was driving a Plymouth Volare' staff car that was huge compared to most cars there.) Took about a week to relax after driving in Seoul. I saw a motorcycle run smack into the back of a stopped bus, and had a truck with a roll of steel in the bed roll over right in front of me. It was a crazy place.
