A new study shows that sharing cabs could make our taxi system up to 40% more efficient. But, would you really share a cab with a stranger just to save a few bucks (and gallons)? Carlo Ratti, director of the MIT Senseable City Laboratory, and Cornell applied mathematics professor Steve Strogatz co-authored the study that crunches NYC taxi data -- they discuss what it can tell us about the future of getting around in NYC.
