Tesla's approach to full self-driving is different from that of autonomous "leaders" like Waymo and Cruise. Instead of relying on an army of sensors like LiDAR and high-definition maps, Tesla is practically betting its future on a vision artificial intelligence approach. The idea is simple: if humans could effectively drive with their eyes and brain, then cars should also be able to navigate safely with a suite of cameras and a trained neural network. This approach has caused a lot of controversy and criticism against Tesla and its FSD strategy. A yearly report from Guidehouse Insights, for example, consistently ranks Tesla dead last among companies currently working on autonomous driving technologies.
