content: I can't imagine very well. Google may have figured out a lot about cyberspace, but meatspace is another thing entirely. Granted, they've pulled of a bunch of astonishing feats. But they've had their failures as well, just not as visible.  I'm on the fence what to think about it in general. Less traffic, less cars, less emissions? Awesome. But the price is huge - effectively centralization of transportation, and that with a at times shady company which is not necessarily acting in its users best interest, but in its shareholders.
