I�m sure you know this situation: you wait in a traffic jam or at a traffic light, you look into a car and imagine, from where the driver comes and where he�s heading to. Why you can get into a traffic jam - a thought experiment: the reader looks at a man at the expressway. What do his actions mean? Did something spectacular happened or something trivial? The text tries out different constellations and combinations, again and again. Although you can find some hints in the text  you can�t find out the man�s secret because you only look from outside.
