If your teenage years are long gone and you still haven't bothered to get a driver's license, you're not alone. According to a recent study, the percentage of people with a driver's license decreased across all age groups between 2011 and 2014. And, while the decrease began for those over 44 around 2008 and for those over 69 around 2011, there has been a continuous decrease for those 16 to 44 years old since 1983.
