It’s 2013. I’m supposed to be riding in a flying car. You are, too. That was the promise we absorbed as children, our imaginations stoked by sci-fi stories, The Jetsons and Marty McFly in Back to the Future Part II. We aren’t in flying cars yet, however, which is why every scrap of news related to them is another ray of childish hope. The latest news has those rays flying around in abundance.
