 Unfortunately, currently, there are no legally operating, fully autonomous vehicles in the United States or other parts of the world. There are, however, partially autonomous vehicles—cars and trucks with varying amounts of self-automation, from conventional cars with brake and lane assistance to highly-independent, self-driving prototypes((https://www.ucsusa.org/resources/self-driving-cars-101)).  Unfortunately, currently, there are no legally operating, fully autonomous vehicles in the United States or other parts of the world.

 The second-largest autonomous vehicles fleet consisting of more than 180 vehicles is deployed by General Motors’ Cruise division (https://www.getcruise.com/). The developing team puts a great emphasis on achievements in AI and robotics. However, a major part of the onboard hardware is made by the Cruise team as well.  The second-largest autonomous vehicles fleet consisting of more than 180 vehicles is deployed by General Motors’ Cruise division (https://www.getcruise.com/).
