A computing system for a vehicle includes one or more processors for controlling operation of the computing system, and a memory for storing data and program instructions usable by the one or more processors. The one or more processors are configured to execute instructions stored in the memory to determine when the vehicle is currently in a user-selected predefined driving situation and, responsive to the determination, control operation of the vehicle to implement a vehicle response mode associated with the user-selected predefined driving situation. The vehicle response mode may include an initial control mode specifying one or more initial indicators of the vehicle response mode, and a conditional secondary control mode specifying one or more secondary indicators of the vehicle response mode. The one or more initial indicators and the one or more secondary indicators are configured to be perceivable by a person exterior of the vehicle.
