If personal automobiles are no longer necessary or interesting to young adults, could there instead be some interest in portable personal vehicles in the future? By portable personal vehicles, I mean not a folding bicycle but something truly portable that would fit in a carry bag -- something like a wheeled version of the hovering, skateboard-like item from Back to the Future, a Segway without the handlebars, a self-balancing scooter or hoverboard.
Portable Personal Vehicles
Could we be seeing the end of car culture in America? We may already be seeing some signs of that. Young adults and teens are less interested in getting drivers licenses. Car buying has also shifted away from the 35-44 age crowd to the 55-64 ages, although this doesn't take into account what will happen when Millennials have kids that need rides to soccer practice or school plays.
Lexus Slide Hooverboard
Carmaker Lexus has actually built a levitating Slide Hoverboard that works over ground and water as well. The device was conceived as a marketing stunt for new Lexus cars, to "make the impossible possible" and it requires special magnetic technology embedded in the ground to make it hover. Unfortunately, it's doubtful that there will be any commercial versions available for sale in the near future.
