1. An automatic lane following system of a vehicle, comprising:
a controller programmed to have an operator offset request defining a lateral offset distance away from a first travel-line of the vehicle in a first displacement path until a second travel-line of the vehicle is achieved, wherein the lateral offset distance is bounded by a lane in which the vehicle is traveling, and the second travel-line is within the same lane as the first travel-line;
a steering wheel;
an operator input setting system when actuated generating an initiation signal forwarded to the controller to input the operator offset request, a switch of the operator input setting system depressed by a vehicle operator to generate the initiation signal;
the operator input setting system communicating a status of lane centering with offset to the operator through a human machine interface (HMI) communication;
the offset distance achieved by a manual rotation of the steering wheel in a selected direction of offset driving after depression of the switch;
a default center position of the steering wheel returned to after achieving the offset distance; and
a second actuation of the switch generating a second signal saving the offset distance.
