Today, Uber is promising flying cars.

Flying. Cars.

Within a decade, according to a 99-page white paper released today, Uber will have a network—to be called “Elevate”—of on-demand, fully electric aircraft that take off and land vertically. Instead of slogging down the 101, you and a few other flyers will get from San Francisco to Silicon Valley in about 15 minutes—for the price of private ride on the ground with UberX. Theoretically.
