A good friend told me once that in the course of a language lesson he had asked his tutor how to say “traffic lane” in Amharic. His tutor just looked confused - the concept was lost on her. On some main roads you may find white lines, but as you observe traffic using the line as a guide to drive on (as opposed to between) or more usually ignoring the lines altogether, you realise the concept is lost on most drivers as well.
