GPS and positioning technology has provided us with our next great leap in making our life more efficient and productive just as computing and the internet has transformed our work and social life. A significant part of our brain is hardwired to understand positioning and where we are in relation to other people and things. Think about standing in the elevator with other people, its mostly uncomfortable because of the close proximity of other people.
Turns out, though, that 100% relying on GPS positioning could be dangerous. In the last years, there have been a handful of incidents of people following their GPS directions into one-way streets, cliffs and even oceans. It might be prudent to have a live person help you navigate when you are driving into that approaching ocean.
