11. A driving assistance system for a vehicle, the driving assistance system including a prediction subsystem and comprising: a component adapted to accept an environment representation representing at least one entity, wherein the at least one entity comprises at least one of a static or a moving object, or a structural element which is detected by one or more sensors in an environment of the vehicle; a component adapted to apply one or more plausibility rules on the environment representation; a component adapted to calculate a confidence estimate related to the environment representation according to a result of the application of one or more plausibility rules on the environment representation, wherein each plausibility rule comprises a plausible relation between the at least one entity and at least one another entity; and a component adapted to provide the confidence estimate as input for an evaluation of a prediction based on the environment representation, wherein the confidence estimate is an estimate of a degree of influence by the detected entity on the prediction, and wherein the driving assistance system is configured to perform at least one of an active control and passive control of the vehicle based on the prediction.
12. The system according to claim 11 , wherein the prediction subsystem is adapted to perform a context based prediction and a physical prediction.
