A vehicle system for use in a vehicle for at least partially automated driving or parking, the vehicle system comprising:

• a first operating mode, which is configured to execute a functionality of the vehicle system in driving operation based on acquired sensor signals and to operate the vehicle in an at least partially automated manner by interventions in vehicle guidance based on a result of the executed functionality, and
• a second operating mode, which is configured:
• to change a degree of effectiveness of the interventions in the driving operation and a degree of effectiveness of an operation decoupled from the vehicle guidance,
• to execute a functionality of the vehicle system with a changed degree of effectiveness of an intervention in the vehicle guidance and a changed degree of effectiveness of the operation decoupled from the vehicle guidance, and
• upon execution of the functionality of the vehicle system with the changed degree of effectiveness of the intervention in the vehicle guidance and the changed degree of effectiveness of the operation decoupled from the vehicle guidance, to acquire operating data of the vehicle and/or feedback data of a user of the vehicle and make the operating data of the vehicle and/or the feedback data of the user of the vehicle available for further use.
