Elon Musk took to the stage at the Vanity Fair Summit ahead of the Big D unveiling, and in addition to talking about how we all could be living in a Matrix-style virtual reality and the perils of our current patent system, he made the obvious case against flying cars. When asked by reporter and Steve Jobs biographer Walter Isaacson about the perpetual promise of cars that fly, Musk hit the nail on the head. “I’m not sure about flying cars,” Musk said. “If the sky was full of cars flying all over the place, it would affect how things look, the skyline. And it would be noisier and there would be a greater probability of something falling on your head. Those are not good things.” All true. Not to mention the licensing, the safety, the economics, the regulation, the fact that the average American can’t put down their damn phone for three minutes to drive their car… You get the idea.
