The lane divider is described in the manual as this:
The LANE DIVIDER is six feet tall and approximately 27 feet long. It is constructed of 1-1/2 inch O.D. steel pipe and connecting hardware, forming railing panels. The openings in the railing panels are filled with clear plastic to prevent portions of ROBOTS from inadvertently passing through the structure.
So, it is clearly impossible to go through the lane divider, since it is filled with plastic.
