This is extremely interesting and I'm looking forward to seeing where this goes. I do have one, perhaps important, question which is currently on my mind. With normal cars we have specific road signs and traffic lights along with regimental layouts in the road in which we follow to get to a specific destination. However, with these new flying cars, how will they make sure one doesn't crash into another? It wouldn't be nice if it was like a floating layout of holographic roads, do you think it would be much more free? Like a plane or helicopter for example?
