Waymo CEO explains why Tesla’s camera-only self-driving system falls short

Waymo co-CEO Dmitri Dolgov explained at Y Combinator Startup School that camera-only autonomous driving systems, like Tesla’s, face a safety ceiling due to the "weak sensing" nature of cameras. While cameras can match human perception and suit driver-assist features, they fall short of the requirements for full autonomy and superhuman performance. Waymo employs a sensor suite combining cameras, lidar, and radar, each serving distinct functions: cameras provide high resolution and color, lidar measures 3D structure, and radar detects velocity and adverse weather. This sensor fusion overcomes sc

• Waymo uses cameras, lidar, and radar to enhance environmental perception.
• Each additional 'nine' in reliability requires 10 times more effort.
