an external sliding threshold configured to be coupled with an exterior surface wall of a vehicle having a sliding door panel that moves to open or close a doorway, the external sliding threshold coupled with the exterior wall of the vehicle outside of the sliding door panel, the external sliding threshold having a first free outer end;
an internal sliding threshold having a second free outer end, the internal sliding threshold and the external sliding threshold disposed on opposite sides of the sliding door panel; and
a coupling plate connected with the first free outer end of the external sliding threshold and the second free outer end of the internal sliding threshold to drive the external sliding threshold from a retracted state where the external sliding threshold does not laterally extend across the doorway to an extended state where the external sliding threshold extends across the doorway, the coupling plate driving the external sliding threshold by movement of the internal sliding threshold, the external sliding threshold configured to provide a threshold surface on which one or more passengers enter the vehicle via the doorway or exit the vehicle via the doorway in the extended state.
