Millennials have produced plenty of anxiety for automakers. As the stereotype goes, entitled young adults would prefer to hail an Uber, take public transportation or even hitch a ride from Mom instead of driving; an unusually large number of young millennials haven't even bothered to get a driver's license. That's led to fears that the largest generation in the country -- defined as people born between 1980 and 2004 -- has abandoned what used to be one of the biggest rites of passage into adulthood: buying a car. But after much hand-wringing among automakers and industry groups, recent data paint a more nuanced picture of millennials' automobile purchasing habits. They reveal a large, diverse group with complicated views about cars -- ones that are fundamentally different from that of previous generations.
