Laser Sensors LIDAR (or light and radar) sensors serve as the eyes of self-driving cars. Usually mounted atop the roof of the car, these sensors monitor their surroundings by shining a light on an object and then measuring the time needed for it to bounce back. But the LIDARs being used today, such as those early designs of Google’s autonomous cars, are too large and too expensive. According to WIRED, researchers at UC-Berkeley say they’ve developed a new breed of laser tech that could reduce these hindrances and could even lead to a broader range of autonomous vehicles. So, What Do You Think? Google’s self-driving car tests in Austin are already proving that humans can’t drive as efficiently as computers. All 16 of the accidents were the fault of human drivers. All signs point to the arrival of self-driving cars — perhaps even sooner than we think.
