In the recent past, the spread of GPS based navigation has been impressive, with a number of drivers using these apps to navigate their way around unknown parts. They are mostly accurate, but every once in a while there is a situation where it shows that people are starting to depend on GPS almost entirely, and end up in strange situations. There have been cases where people have been sent down one-way streets, once a large load was sent down a street where it was difficult to get out of, but even these were seen as somewhat funny situation (although the people directly involved would not see them as funny).
But this particular situation in Australia is pretty bad. Most of Australia is barren land, a sort of desert with very few people and large sections without telecom coverage. So when the Apple Maps started sending people through a dirt road and into a desert like area where there was no telecom coverage, no water, and sand that would cause vehicles to get bogged down, it started worrying the police. They had to keep coming in to rescue people and worry about whether people might die in the heat and without water, and so the police have blamed the app for causing people to get off the highway and threatening their lives (link to article):
The Murray-Sunset National Park is in Victoria's far northwest, a relatively untouched semi-arid region accessible only by four-wheel-drive vehicle. Clemence said at least six vehicles had become stuck on the desert park's sandy tracks after being directed by the iOS mapping system to turn off a long and infrequently sign-posted stretch of highway between South Australia state and Victoria. "These people have still been rescuable. But we've just had a 46C day (115 degrees F). If they were out there in that temperature and out of phone range, they would have been in serious trouble," he said.
