Overtaking on rural roads often becomes dangerous when oncoming traffic is detected by the driver too late or its speed underestimated. Recently proposed cooperative overtaking assistance systems, which are based Vehicular Ad hoc NETworks (VANETs), rely either real-time video transmission exchange of status messages (beacons).
