"Fortunately there were not turns involved during that portion of the trip."
Which implies that, if there had been turns, that would have been unfortunate. Which implies that something bad would have happened - namely, the parent getting lost.
Personally, I could never understand people who relied solely on GPS for directions. Yes, it's very handy to have. But what if the battery runs out? Software or hardware error? Or, these gaps in coverage, which I didn't even know happened? Before any trip to a new place, I always trace the route on Google maps, and print it out. This way, not only do I have a hard-copy backup of my directions, I am also able to customize my route (which is oftentimes better than what my GPS picks). Not to mention, looking over the maps beforehand familiarizes me somewhat with my route and what's around it. This is ESPECIALLY important if I'm going on a long trip through multiple states that I'm totally unfamiliar with, like the parent.
You just don't get any of those benefits when all you do it get in your car, turn the ignition, and wait until the robot voice tells you when to turn.
