"I would imagine that this is probably different than just making more time for people to click on web sites," --director of Google's self-driving car group quoted in article.
I'm sure he just meant that Google's standard business model won't apply--they will need to actually have people pay to either own or license the technology, rather than freeing time for them to use Google's traditional revenue sources. I imagine the interviewer had to ask a pretty silly question...
Freeing up time is enough to sell billions of dollars worth of these cars--more, to make people spend billions of dollars *more* on cars than they otherwise would--in New York and Los Angeles alone.
Also, the automakers are used to living in a litigation-averse culture; self-driving cars are going to make it a *lot* easier to determine who is at fault in court cases.
