This way of thinking is heavily ingrained into the Swedish traffic laws, where a key point is that there exist no rights in traffic, only obligations. If there is an accident there is generally two parties at fault. One party can be at more fault (which courts/insurance companies cares about a lot), but every driver, cyclist, and even pedestrian are directly responsible to prevent accidents. This also apply to boat captains. People have gotten in legal trouble for strictly following the rules in places where common sense implied that doing so unnecessary caused an accident. This mind set means that anyone on the roads or on the sea should never assume or trust any other participants, and thus to the best of a person ability communicate intend, verify that everyone is behaving correctly, and apply a defensive posture in order to create margins against unwanted outcomes.
