According to the National Highway Traffic Safety Administration (NHTSA), in 2015 alone, 3,477 people were killed and 391,000 were injured in motor vehicle crashes involving distracted drivers. During daylight hours, approximately 660,000 drivers are using cell phones while driving. That creates enormous potential for deaths and injuries on U.S. roads. Teens were the largest age group reported as distracted at the time of fatal crashes.

Perfect storm

Some of these incidences are the result of a perfect storm. The rate of teen crashes rises during these “100 Deadliest Days” — the hot summer months — because teenagers are now out of school for the summer and thus, on the road more frequently. Families buoyed by the recent, well-timed drop in gas prices — falling 2.6 cents per gallon in the last week to $2.25 per gallon, according to gasoline price website GasBuddy.com — will soon be in the car more, likely kicking off road trips to commence with the July 4th holiday. Coupled with any kind of driver inexperience or distraction creates for a risky, often deadly combination.

While foldable maps don't present the driving distraction they did decades ago, there are now many more distractions that present while driving, including cell phone use, which is at the top of the list. Almost everyone has seen a driver distracted by a cell phone, but when you are the one distracted, you often don't realize that driver is you.
