Is Tesla's Elon Musk wrong about this key self-driving technology?

Elon Musk is reportedly launching an investigation into an employee who sabotaged the company. Elon Musk, Chief Executive Officer of Space Exploration Technologies Corporation, speaks on the final day of the 68th International Astronautical Congress in Adelaide, Australia, on Sept. 29, 2017. Elon Musk has called lidar a crutch. The Tesla CEO believes he can build self-driving and semi-autonomous cars without relying on the technology, which uses lasers to help the cars map and navigate their surroundings. Instead, Tesla has looked to cameras and radar -- without lidar -- to do much of the work needed for its Autopilot driver assistance system.
