Apple recognized a few months ago that its map app was so inefficient that it encouraged using a competing app, but now the police in Australia suggest such a move might save the lives of motorists Down Under.

Police in Victoria, Australia, issued a warning Monday discouraging iPhone users from relying on Apple’s map app after rescuing several people who became stranded in recent weeks in the wilderness following the app’s directions — some who were stranded 24 hours without adequate food and water.

Update: According to The Register, Apple has fixed this error.
