Uber goes public today. Private investors will count their millions. Or billions. It’s time, therefore, to look at its public promises.

When the ride-sharing companies made their debut—Uber in the US in 2009 and Ola in India in 2010—a common belief was they’d reduce congestion, private vehicle use, and commute time. Not only is there no evidence to these changes—the average commute time in Indian cities continues to get longer—it’s now clear that before things get better, they’d get worse.
