Have experienced similar dust storms around Broken Hill but never kept on driving like these two guys in the video! With visibility next to nothing it is a recipe for disaster.
Well, the Aussies don't have anything on us when it comes to the stupid department. Every year there are desert or prairie or high plains dust storms that people go driving into and ram into something. Also the highway department posts signs 'do not drive into smoke' to alert people not to try to drive through thick smoke from the inevitable prairie fires, but we always have a few who crash their cars or trucks from that too.
