Scenario one: A traffic police officer flags down an overlapping matatu. The driver seems to ignore the order, but the officer stands his ground. The crew has to explain why they are flagrantly disobeying traffic laws and putting the lives of other road users in danger.
However, something interesting happens upon arrival at the police station. The officer receives a call from "above". Minutes later, the matatu is back on the road, its crew totally unfazed.
