The invention provides a cognitive overload sensing system for a vehicle, the vehicle comprises an autonomous driving system, wherein the cognitive overload sensing system comprises: at least one sensor; a processor configured to determine a cognitive load parameter for a driver of the vehicle based at least on data from the at least one sensor; wherein the processor is further configured to: suppress notifications to the driver if the cognitive load parameter is determined to be above a first threshold value; and increase an autonomous driving level if the cognitive load parameter is determined to be above a second threshold value. The sensors may detect inside or outside of the vehicle and be able to determine cognitive load based on location data.
