2018-07-29: In the 1930s, New York building commissioner Robert Moses built one highway and bridge after another, with the aim of relieving congestion in America's biggest city. But each time, the result was the same: worse traffic.
Today, Uber and Lyft are making traffic in major cities even worse because people tend to take them instead of walking, biking or taking mass transit, say multiple studies. Net effect is 5.7 *billion* additional miles of driving in 9 major U.S. cities
Ride-hailing apps and robot cars promise to change how we get around and the effects are already being felt.
