Leave it to the aussies to have so many Landcruisers, they can turn them into an emergency network! Feel free to move this, I just figured it was a pretty cool approach to a safety system. Don't need to be actively monitoring your radio for distress calls, instead your rig just passes the data along until it reaches the intended recipient!
