I think we all see where Google is headed with this: free self-driving cars in return for advertising, like http://www.kahdo.com.au/kahdo.htm http://www.kahdo.com.au/kahdo.htm Driver, there's items you like on sale at that store. Driver, I think we should stop and check it out. Driver, we are stopping. Dear, I don't feel safe having Lisa drive with that new Mark boy. You can just tell he dials aggressive. But seriously, from a marketing perspective, I think the low-hanging fruit here is highway driving. It's a small, logical and therefore adoptable step up from cruise control, just with a little auto-steering (they already have auto-braking IIRC), and perhaps some networking for predicting lights, congestion and co-ordinating with other (online) cars. Start with an "online-only" lane.
