I was recently driving around in the San Frisco area, of California. I had a brand new Android tablet with moving map for navigation.
This articular tablet was having some issues and stopped navigating at a few critical points. I felt quite helpless. I've been driving around in the same area off and on for decades, and when using a paper map, was always able to maintain some sense of situational awareness.
The GPS-based map has a whole lot more useful information and flexibility, which is why I use it. But, It's a little scary how dependant I've become on it so quickly.
