The drones each feature both battle lasers and sensors to detect when the they’ve been illuminated by another drone’s, so you can stage aerial battles. When a drone is “hit” it descends to the ground.

A drone that flies you

At the far more expensive end of the spectrum is the Ehang 184, drone designed to take a single occupant on short trips. I first saw this at last year’s CES, when the marketing pitch suggested that the drone could streamline the commutes of particularly rich individuals. A year later, prototypes have undergone more than 200 remotely operated flight tests in China, and the company is no longer pitching this as a particularly ostentatious form of personal transportation. The publicist I spoke to instead suggested higher-minded uses like medical transport.

But even if the $300,000 Ehang 184 ships as promised, I’m sure some dot-commer will buy one just to get around town. And, of course, will take a drone selfie in mid-flight.
