1. A method that is computer-implemented and is for steering assistance, the method comprises:
processing, at a machine learning process an image obtained by a camera of a vehicle of an environment of the vehicle; and
directly mapping in a single step and in real time, by the machine learning process, road line metadata that comprises a line offset value, a line angle value, a line curvature value and a line curvature rate; the road line metadata facilitates a steering related response;
wherein the line offset value is indicative of a lateral distance between the vehicle and a road line;
wherein the line angle value is indicative of an angle of the road line in relation to vehicle progress direction;
wherein the line curvature value is indicative of an amount of steering required for maintaining the vehicle within a road line that is curved; and
wherein the line curvature rate value is indicative of a rate of steering change required to maintain the vehicle within a curved lane segment, when the vehicle enters or exits a curved lane segment that is delimited by one or more road lines.
