 The `HostVehicleData` interface describes the measured internal states of a traffic participant.
 OSI currently provides only limited support for data structures that describe measured internal states of traffic participants.
-One example would be the `MotionRequest` interface that can be used to commuciate the results of the behavior planning to the dynamic model.

 The following figure shows a more advanced use case for traffic participants, that can, for example, be used to model an autonomous vehicle.
