The non-driving Millennial was a myth started during the Great Recession, as an inordinate number of them were delaying getting their driver's license, buying a car and moving out of their parents' basements. That's what happens when "experts" formulate future trends based on abnormal points in time. It turned out that as the recession ended, Millennials started getting jobs, buying cars, getting married and moving out.I'm not so sure about that. The future has a nasty habit of taking so many bends in the road that it's difficult to predict what people are going to want or not want.
There have been any number of life-style and culture reports and features mentioning that many Millenials have no urge or desire to own a vehicle of any kind. Suppose this is only the tip of a very big iceberg...not to mention any number of factors and circumstances which will take the automotive industry in directions we haven't even thought of.
Teens are still delaying getting their driver's licenses. That's supposed to be related to not needing to leave the house any more to socialize. But landing a job, getting married and having children remain key triggers for vehicle purchases. Millennials have been fueling the healthy auto market we have had in recent years, and now account for the majority of new-vehicle purchases.
