The Navya Arma Is Hauling People Around Las Vegas With No Driver

No, the Arma demonstration did not take place on public roads, even though the electric vehicles are capable of that.

The Arma figures out where it is thanks to Lidar, cameras, and odometry. The first time the vehicle drives a route, it needs to be driven manually by an engineer using a joystick. Once the route is set, then the joystick is removed and the car doesn't have a steering wheel back up.
