An elderly man has died after his car rolled down a hill at Saddleback Mountain this morning. The man, believed to be in his 80s, collapsed at the wheel on Williams Road in Kiama just before 9am. A NSW Ambulance spokesperson said a female passenger called triple-0 but while she was on the call, the car started rolling backwards. It eventually came to a stop but the woman suffered head injuries. She was taken to Shellharbour Hospital in a stable condition. The man died at the scene.
