Uber has a plan to make flying cars a reality

Uber already has self-driving cars, and now it's on to the next frontier: Flying cars. The ride-hailing company on Thursday posted a white paper outlining its plan for "on-demand aviation," aka flying Ubers. "On-demand aviation, has the potential to radically improve urban mobility, giving people back time lost in their daily commutes," Uber wrote in its white paper. Along with a lengthy analysis of the economics and mechanics of flying cars, Uber published a bunch of illustrations of next-generation airborne transportation. The plan involves a network of small, electric aircraft that take off and land vertically.
