Tesla relies on cameras and machine learning for its self-driving system. Other companies, like Waymo or Amazon’s Zoox, also use cameras and machine learning, but add LiDAR, which are lasers, and radar to provide more input to the self-driving software. Musk has frequently spoken about leading the autonomous vehicle market, but Tesla has lagged behind competitors. Multiple operators offer services in China, and Waymo is now active in around five U.S. cities, including Phoenix, Los Angeles, San Francisco, Atlanta, and Austin as of March. Roughly a decade ago, Tesla showcased its autonomous technology in the “Paint It Black” video, though it was later revealed that the Autopilot demonstration was staged, exaggerating the vehicle’s self-driving capabilities.
