Google gets license to test drive autonomous cars on Nevada roads
To me, there are only a few "out there" technologies that have a chance to change everything. 3-D printing is at the top of my list, but that's going to be a while before it really takes off. The others are robotics (also taking a while) and self-driving cars.If Google can work through not only the technical but the social and legal problems associated with fully auto-drive cars, it could literally change the world overnight. Instead  of driving cars being a time sink, it could change into something along the lines of being in a room that goes places. You could sleep, read, play games, or otherwise occupy your time. It would literally give the nation tens of billions of hours in added productivity time. It could make the elderly more independent, eliminate drunk-driving, and a lot more. Very cool stuff.
