I think if we want to solve large scale intersectional problems like traffic (where lots of individuals with their own goals and own variables intersect) we will need to give up SOME of our privacy in terms of where we are headed (just heading), speed, car model/make or some kind of capabilities estimate... This could result in a smarter traffic flow, road design, or in Google's case powering safer self-driving cars. I'm up for any of those outcomes and am also concerned about giving up data unnecessarily. I think the crux of the article besides hyping up self-driving simulated driver's better decision making is that roads aren't designed as safely as they could be and some minor inconvenience to the user (time, some data given up) could save lots of lives.
