When you run a shared taxi service and customers step into and out of your ride at different points of the journey – how to you keep track of what to charge each person? This four person taxi meter introduced by Tehran’s taxi authority technically works but according to this taxi driver is not often used. Why? Unpopular with customers more used to a culture of bargaining.

This meter is crudely indicative of the finer granularity of data that increasingly surrounds us. In which contexts and cultures will this measurable/precise data be welcomed, and by whom? In which rejected?
