Tesla CEO Elon Musk criticized the self-driving technology developed by competitors such as Waymo and Cruise LLC, stating that they are "extremely brittle" and do not scale well. He argues that Tesla's self-driving technology is superior because it can interpret real-time information and make decisions accordingly. At the same time, other companies have developed narrow and fragile technology that requires constant supervision. There have been incidents in which Waymo and Cruise cars, have halted mid-road, causing traffic disruptions. Tesla vehicles equipped with Full Self-Driving (FSD) features have received customer complaints concerning self-acceleration and braking problems. Leaked data from Tesla's IT system indicates that some incidents have had fatal outcomes.
