The Uber vehicles are equipped with everything from seven traffic-light detecting cameras to a radar system that detects different weather conditions to 20 spinning lasers that generates a continuous, 360 degree 3-D map of the surrounding environment.
Uber officials said they hope the initial trial will teach them how to ease public fears about the cutting-edge technology.
