HOVER (high occupancy vehicles in express routes) is an efficient carpooling system originally developed in Auckland, New Zealand to reduce congestion.  Hover provides a system that does not require pre-planning for drivers, no commitment to participate everyday, or travel at specific, predesignated times.  Lots of cars commute to similar destinations, and have empty seats, so it’s a great system to reduce highway congestion, and reduce automobile emissions.  The organization advocates that “park and ride” facilities for the “park and pool” system be publicly funded like roads and buses.  Check out the video below.
