Roads? Where we're going, we won't need "roads"

The images and entertainment, even the science, of my childhood promised me two things: becoming a professional athlete is a distinct possibility for anyone; and cars will fly sometime after 2000 (thanks for nothing year 2001).

Maybe we're getting a step closer. Scientists have learned how to levitate...things by reversing the process that allows a gecko to stick to walls, the ceiling, or anything else. I'm still hoping scientists will complete my technological wish trifecta: levitation/flying, invisibility, and teleportation. Let's do it.
