A Tesla's view of the world is provided entirely by cameras, whereas Cruise and Waymo use an array of different kinds of sensors, most critically lidar. Short for Light Detection and Ranging," lidar systems use pulses of lasers to map the environment with impressive fidelity, though at a much higher cost.
