Elon Musk, CEO of Tesla Inc., has reiterated his criticism of LiDAR technology, stating that it is not necessary for self-driving cars. Musk believes that human vision is a better guide for autonomous driving, and that cameras and digital neural nets are sufficient for navigating roads.
Musk’s Perspective
Musk explained his stance on LiDAR during the company’s fourth-quarter earnings call, saying:
Obviously, humans drive without shooting lasers out of their eyes… humans drive with eyes and a neural net and a brain neural net, sort of biological… the digital equivalent of eyes and a brain are cameras and digital neural nets or AI.
He emphasized that LiDAR is the “wrong solution” for self-driving cars on roads, although he noted that his rocket manufacturing company SpaceX uses LiDAR for docking with the space station.
Criticism and Counterpoints
Musk has previously criticized LiDAR, referring to it as a “crutch”. However, not all experts agree with his decision to rely solely on cameras for autonomous driving. Jesse Levinson, co-founder of Zoox, argued that significantly more hardware is needed to build a safe and reliable robotaxi, and that sensor data is essential to protect against camera malfunctions.
Industry Comparison
Other companies, such as Alphabet Inc.’s Waymo, continue to use LiDAR in their autonomous vehicles. This highlights the ongoing debate in the industry about the best approach to autonomous driving.
Conclusion
The decision to use or reject LiDAR technology has significant implications for the development of self-driving cars. While Musk and Tesla are committed to their camera-based approach, others in the industry are taking a more cautious approach, incorporating multiple sensors and technologies to ensure safety and reliability.
