Having driven cars and rode bikes overseas... this is all too common. Especially the passing of a bus as soon as you see it ahead of you. Regardless of line of sight or on coming traffic. My favorite was coming back from an all day adventure, all tired, and seeing a bus coming toward me on a wide straight road. And a car behind it going to pass it. And a car ahead of me going toward it. You can guess the free for all that occurred. I took a quick trip through a ditch (in a car). The surprise, the bus passed a car in front of him, while the car behind him passed the bus, into oncoming traffic ahead of me. Not what I wanted to see. And they probably all thought it was ok, since the road was so wide. Not to me, it wasn't. No better than a three lane road back home, with wet ditches on both sides.
