A computer-implemented method is provided for automatically guiding a first vehicle to maintain a position relative to a second vehicle traveling in a given area. The method includes the steps of: (a) receiving location data on the first and second vehicles; (b) determining a legal travel path in the given area from the first vehicle toward an expected position of the second vehicle; (c) automatically controlling the first vehicle to travel along the legal travel path; and (d) repeating steps (a) through (c) to automatically move the first vehicle to a relative position from the second vehicle and then to automatically maintain the relative position as the first and second vehicles travel through the given area.
