Most companies involved in vehicle autonomy believe that adding more sensors of various types improves accuracy and safety. Robotaxi companies are the best example, with their cars crammed with massive sensor arrays comprising radars, lidars, cameras, and ultrasonic sensors. These companies rely on high-definition map data to offer precision positioning.
