Uber CEO Travis Kalanick's Gridlock Solution? Carpools For All

IN THE CLASSIC SCI-FI NOVEL "the Hitchhiker's Guide to the Galaxy," an alien visiting Earth names himself Ford Perfect based on the assumption that cars are the dominant form of life on this planet. It's an understandable mistake when you look at our cities today. These hunks of metal consume vast amounts of our money, space and natural resources--and sit idle 95% of the time. At the beginning of the book, the Earth is destroyed to make way for an intergalactic highway. But unless we rapidly reimagine urban transportation, cities risk imploding under the weight of more than a billion cars.
