Maps are good for your brain. Really. By using a map you are forced to memorize things, and they help you orient yourself. Most animals, including us have an inate ability to navigate, and maps help us. Some apps especially the devices in cars that tell you to "turn left here" etc. don't engage your brain and the part of your brain devoted to navigation will atrophy.

Roads in New England are also in terrible shape, especially after winter, with its freeze-thaw- refreeze cycle. Thats why I have 42mm wide tires on my bikes.
