You could end up like the lost woman and her kids rescued from Elk Island Park who was following hers and ended up 4 km. off course!
There have been many other more disastrous stories of drivers ending up on dead end roads and even in remote uninhabited places having put their full blind trust in technology.
Using a modicum of common sense and built-in human smarts is a wise practice rather than turning one’s own safety and that of other loved ones completely over to technology, which has a track record of failure and tragedy.
