net 6 shown here in a raised position net 6 may be supported that is raised and lowered by pillar 10 ramp 12 may allow vehicles to pass over net 6 when net 6 is in a lowered position in one aspect energy absorbers 8 may include a length of synthetic material that is woven together and that absorbs or dissipates energy when pulled apart as shown in fig1 b and described in more detail below in one aspect of the system of the present disclosure when net 6 is in a raised position vehicle 1 may strike and impart force on net 6 upon application of a predetermined threshold force from vehicle 1 net 6 may uncouple from pillar 10 as impact by vehicle 1 continues net 6 may apply force to energy absorbers 8 energy absorbers 8 may be coupled to anchors such as anchor pads 4 when energy absorbers 8 are woven material the force from impact by vehicle 1 may rip apart woven material in energy absorber 8 thereby absorbing or dissipating energy and causing vehicle 1 to decelerate fig2 a and 2b show a barrier with net 6 in upright and lowered positions respectively net 6 may include horizontal members 200 and vertical members 204 that may be coupled to energy absorber connector 206 and pillar connector 208 in one aspect net 6 may be woven multi ply synthetic material while energy absorber connector 206.
