A field monitor system of a vehicle for performance monitoring and evaluation of an ADAS or autonomous driving feature of the vehicle. The field monitor system stores, during a time period ranging from a first time point to a second time point, a range of perception data on which the ADAS or autonomous driving feature is pertinent derived from a perception system adapted to estimate surroundings of the vehicle. The field monitor system determines ground truth intermediate data at the intermediate time point. The ground truth intermediate data reflects estimates of vehicle surroundings at the intermediate time point conditional on the portion of the range of perception data. The field monitor system determines an accuracy deviation measure indicating deviation between the ground truth intermediate data and the intermediate perception data. The field monitor system further communicates acknowledgement data when the accuracy deviation measure exceeds a performance threshold.
