The glory of Google Maps is how you can conduct a tour through areas you are about to drive around and learn the lay of the land. I tend to do that out of habit now as plan out which hotels to take, figure out what to expect, etc. The value to me is being able to relax a bit during a drive and not face last second choices in navigation. My phone pulled double duty this past January during my cruise on Oasis of the Seas. Mounted just under the rear-view mirror, I kept the video camera rolling as I drove through downtown Atlanta. Always a busy highway, the drive was smooth enough until some concert letting out flooded the south side exits along I-75.
