1. A method for maintaining a driver's perceived trust level in an at least partially automated vehicle, comprising:
monitoring parameters concerning the driver, the parameters comprising information related to a driver profile, including stored driver preferences concerning vehicle dynamic outputs and human-machine interface outputs to the driver;
predicting, based on the parameters, a decrease in the perceived trust level;
carrying out one or more countermeasures to compensate for the predicted decrease in the perceived trust level;
updating the stored driver preferences in response to the predicted decrease in the perceived trust level;
detecting and monitoring contextual information indicating misbehavior of another driver that contributes to the decrease in the perceived trust level, the misbehavior including zigzagging.
