Tesla’s self-driving feature relies on a network of cameras, sensors, and other technology to provide a seamless experience. Yet, as studies have shown, the technology’s not quite there when it comes to eliminating auto accidents. Not all Teslas come with the latest self-driving technology. As the auto manufacturer states, Teslas produced from September 2014 to October 2016 come with the first-generation self-driving technology, which comprises one camera, ultrasonic sensors, and a first-generation radar. They cannot receive retroactive outfitting to accommodate the latest self-driving technology.
