What happens when the GPS says one thing, and the "internet" says another?
what takes precedence?
The "Internet" isn't safe, reliable or even bullet proof.
New technology isn't a golden bullet. Often its just a re-invention of the wheel. (whatsapp for example, is just MMS without the guaranteed delivery.)
I don't want my plane being crammed full of shiny new tech, especially if its not proven. Th reason why there is bureaucracy is to make things safe.
