  • the raw data stored in the raw data memory in the data processing unit can, for example, provide a more reliable traceability of past processes in the event of subsequent discrepancies due to misuse or an accident with the vehicle.
  • the raw data can identify measured values from acceleration sensors or structure-borne noise sensors. This can also increase user acceptance of car sharing. Since the blockchain values 68 make it possible to understand which data arose during the use of the vehicle, incorrect assignments, for example of vehicle damage, can be corrected using the raw data. Saving the raw data also makes it possible to use evaluations for this purpose, which were only created subsequently. For the car sharing provider, there is the possibility that the charges for the use of the vehicle can be adjusted depending on the driving behavior of the user 100 and thus the costs for car sharing should decrease.
