1. A heads-up display system for a vehicle, comprising:
a display area on a surface of the vehicle;
an optical projection unit for projecting graphic elements to the display area; and
an electronic control unit operatively connected for computer communication to the optical projection unit, wherein the electronic control unit:
determines a perspective view of a real road scene as viewed by a user through the display area, wherein the perspective view is based on a ride height of the vehicle and an eyepoint of the user;
identifies road features of the real road scene visible to the user in the perspective view of the real road scene;
adjusts a virtual image having inclined content based on the road features so that the inclined content substantially matches the perspective view of the real road scene; and
controls the optical projection unit to project the virtual image to the display area.
