Taxicabs

Frustrating as it can be to tell your phone where you're going, we'd bet you've had an easier time explaining your destination to some voice-recognition software than explaining it to a human driver with whom you share no linguistic touch-points. But just to ensure the safety of Taxi Siri, we recommend leaving the Plexiglas barriers in place. And who knows? If you can call for your robo-car to come pick you up, the taxi might find itself on the wane.
