That is the wrong conclusion from what I explained. In the example of a 7-lane road with no painted markers, the cars in the right most lane, tracked a fine straight line, actually further from the curb than with lines, when no lane makers were present. It was the cars in the middle lanes that had more difficulty trackinga straight line as the nearest point of reference was 24ft to their right.
