Uber could teach its AI to know when you're drunk

Problematic transportation outfit Uber is thinking about a way to use your phone to determine if you've been drinking. A patent application was uncovered by CNN, entitled "Predicting user state using machine learning," which outlines the general idea. Essentially, by watching how you behave day-to-day, the system can pick up when your behavior is normal (for you) or abnormal. That could be, for instance, how you use your phone, the angle at which you hold it, and even how you're walking. Obviously there are some common sense elements to this, too, especially if you're requesting a ride in the small hours from a notorious night spot.
