System and methods for a vehicle for determining driver distraction and adapting the operation of driving assistance systems. One example system includes a subsystem for sensing driver interaction with electrical devices located within a passenger compartment of the vehicle, a first sensor configured to sense conditions outside of the vehicle, a second sensor configured to sense conditions outside of the vehicle, and an electronic controller. The electronic controller is configured to determine a state of driver attentiveness based on driver interactions, provide the driver attentiveness state to a driver assistance system, determine a threshold of the driver assistance system based on the state of driver attentiveness by adjusting at least one of a sensor fusion confidence threshold, an object classification confidence threshold, a lane association threshold, blind spot detection threshold, or lane detection warning threshold; and control the vehicle via the driver assistance system operated in accordance with the threshold.
