Wow, watch that full screen, sitting close. I can see why Hadrian said, screw it, build a wall.
The pull outs (lay bys?) are on both sides of the road, wherever there was room I suppose. So do you have a choice of pulling into one if it's on your side or stopping next to one if it's on the other side, so the oncoming driver can use it to get around you? I suppose the natives have an understood protocall, probably unwritten, but how does a tourist know the proper etiquette?
