It only took emergency services eight minutes to respond to a car crash early on Monday morning in Tasmania's north, after one of the passengers' phones detected the incident and made the call.
Police were automatically notified after the four-wheel drive crashed into a tree stump at 1:45am, and five people were taken to hospital.
It is not the first time the feature has led to the rescue of drivers caught in accidents — earlier this year, the feature alerted authorities to a crash in remote southern Tasmania when an 18-year-old was trapped, and in Adelaide after a man's car was hit by loose truck tyres.
