1. A system comprising:
a processor; and
a memory in communication with the processor, the memory having a human-machine interface module having instructions that, when executed by the processor, cause the processor to:
identify, based on sensor data regarding a vehicle and an environment in which the vehicle operates, an event in which the vehicle should perform an autonomous steering maneuver determined by an autonomous driving system;
in response to identifying the event, decouple control of a steering rack of the vehicle by a handwheel of the vehicle and lock the handwheel to prevent the handwheel from substantially moving;
identify a direction of an isometric torque input applied to the handwheel and detected by the processor via one or more sensors of the vehicle when the handwheel is locked, the direction being one of clockwise and counterclockwise;
determine, by the autonomous driving system, the autonomous steering maneuver to be performed by the vehicle based on the direction of the isometric torque input; and
execute, by the vehicle, the autonomous steering maneuver.
