After revealing a first look at its flying car prototype, slated to launch in LA by 2020, Uber looks to further improve its service, as the ridesharing giant has explored identifying drunk passengers with artificial intelligence, according to a patent application.

CNN first reported the patent, which describes a method of measuring the user’s behavior on their phone against their usual behavior. The system relies on an algorithm to weigh a variety of factors, including typos, how precise a user clicks on links and buttons, the speed at which the user is walking, and how long it takes to request a ride.

The patent also suggests that the service Uber provides to the user could change, as a result. Drivers may be warned of their passenger's state, and riders in an unusual/drunken state may only be matched with drivers with relevant experience or training, the patent application says.

Furthermore, passengers might not be given the option to be included in a shared ride, based on their state, and as for Uber drivers, drunk passengers is notably a drawback of the job.
