Bloomberg - A Fatal Tesla Crash Shows the Limits of Full Self-Driving

“There is a reason why Superman could shoot lasers from his eyes, but also uses his eyes for seeing. You want redundancy,” Smith said. “It is shocking to many people that Tesla has such confidence in a single type of sensor.”

"Other automakers and autonomous-driving technology companies also use radar and lidar, which emit energy — in lidar’s case, laser pulses traveling at the speed of light — to detect the distance of surrounding objects. As active sensors that generate their own signals, they’re not affected by external lighting conditions and function better than cameras in direct sunlight."

"One advantage cameras have over both radar and lidar is cost. Analysts at BloombergNEF estimated in a report late last year that the sensor suite on a Tesla Model 3 costs just $400. The researcher said that the 40 sensors on the Jaguar I-Pace SUVs that Waymo had deployed in states including Arizona cost 32 times more: roughly $12,650 per vehicle."
