ADAPTATIVE CRUISE CONTROL EXTENDED AUTO-RESUME FOR NON-CONTROLLED-ACCESS ROADWAYS

A system comprises a computer having a processor and a memory, the memory storing instructions executable by the processor to determine, as a vehicle travels along a roadway while an adaptive cruise control feature of the vehicle is active, that the roadway is a non-controlled-access roadway, detect a presence of traffic congestion impeding travel of the vehicle along the non-controlled-access roadway, responsive to detecting the presence of the traffic congestion, generate a prompt for driver input indicating whether the adaptive cruise control feature is to enter an extended auto-resume (XAR) mode, and cause the adaptive cruise control feature to enter the XAR mode based on driver input indicating that the adaptive cruise control feature is to enter the XAR mode.
