15. A vehicle with a vehicle black box and a main wireless circuit, said vehicle black box comprising:
a sensor interface configured to receive sensor data from a sensor circuit sensing at least one physical vehicle parameter defining a physical behavior of said vehicle, wherein said at least one physical vehicle parameter comprises at least one of velocity or acceleration;
a wireless circuit configured to receive radio frequency signals that are received and sent by the main wireless circuit of said vehicle, said wireless circuit configured to generate in-phase and quadrature (IQ) data based on said radio frequency signal received;
a recording circuit comprising a first memory for temporarily storing said IQ data generated and a second memory for permanently storing said IQ data generated; and
a processing circuit configured to receive and evaluate said sensor data, said processing circuit having an evaluation sub-circuit and a control sub-circuit, wherein said evaluation sub-circuit is configured to take a pre-defined route of said vehicle into account and to identify an abnormal movement behavior that triggers said control sub-circuit to control a transfer of said IQ data from said first memory to said second memory based upon an evaluation result,
wherein the wireless circuit is configured to collect radio frequency signals that are received or sent by the vehicle,
wherein said vehicle black box further comprises data associated with expected movement behaviors due to said pre-defined route of said vehicle,
wherein said processing circuit is configured to access said data and to differentiate between the abnormal movement behavior and a normal movement behavior derived from said data associated with the expected movement behaviors,
wherein said vehicle is an at least partly autonomously operated vehicle,
wherein said main wireless circuit is configured to wirelessly receive control data used to control a movement of said vehicle, and
wherein said wireless circuit is integrated in said vehicle black box and is configured to verify an interference of said main wireless circuit.
