There’s an ongoing battle between LiDAR, Automotive Radar, and Cameras (and a few others too) for the title of the self-driving car’s “eyes:”

But self-driving car do more than just “see” the world. The cars also are equipped with sensors onboard that can tell the vehicle more about the surrounding world and itself. These sensors tell how fast the car is moving; the G-force acceleration experienced by the vehicle in forward-back, side-to-side, and up-and-down directions; the current steering angle; and lots more. It is a combination of these perception systems (camera, LiDAR, Radar) and sensor systems (GPS, IMU, Wheel Speed, etc) that make up the inputs to the “sense” block of the self-driving car AV stack.
