1. A computer implemented method comprising: generating a three dimensional (3D) model of a real world scene within a specified radius from a vehicle, based on a digital mapping source of the scene; associating one or more positions in the 3D model with respective location aware entities (LAE); estimating a current view direction of a viewer in the vehicle; and superimposing three-dimensional graphic symbolic indicators respectively representing the LAEs onto a windshield of the vehicle in specified positions selected according to the estimated current view direction of the viewer such that the viewer, the symbolic graphic indicator on the windshield, and the position of the LAE in the 3D model are substantially on a common line of sight of the viewer, wherein the three-dimensional symbolic graphic indicators comprise at least one three-dimensional direction arrow, wherein the arrows are superimposed on the windshield only some of the time, when considered needed by the viewer to identify a desired turn of the vehicle.
