Uber has applied for a patent to detect drunk passengers. The technology would evaluate behavior using information such as location, data-input accuracy, the angle at which their phone is being held, and the speed at which they’re walking. Riders would then be matched with a driver who has special training — or could be refused a lift entirely. Uber has come under fire over data in the past: The company revealed a massive breach in 2016and last year removed a rider-tracking feature amid widespread criticism.
