@prabhakar, I agree. Hence the difficulty of pulling off self-driving cars. There are so many unseen factors on the road today, when compared to the controlled airspace. But the analogy does apply in a sense that both self-driving cars are marching toward "auto pilot."
@max, Seriously? When it comes to 3D, you do need to accept the fact that it is really going NOWHERE at this point. Even Hollywood is scaling back 3D film production, and there is no TV programs (including sports) in sight offering 3D coverage!
