Uber applies for patent to spot drunk passengers

Taxi app company Uber has applied for a patent to use artificial intelligence to determine how drunk potential passengers might be. The app used to summon rides could also feed other information to the driver, including a passenger's location, how accurately they are typing and even the angle they are holding their phone at. It could help drivers who do not want to pick up inebriated riders. But critics said it could also be used to identify vulnerable passengers. According to the application to the US patent office, the system would spot "uncharacteristic user activity".
