“Electronic data recovered from the vehicle indicated that before the crash, the driver manually overrode FSD (Supervised) by pressing the accelerator pedal to 100%, and the vehicle’s speed was greater than 70 mph when the crash occurred.”
“After the crash, Butler told hospital providers that he remembered 'putting the car in self driving mode' and that he 'passed out.'”
“Authorities found no blood or alcohol in his system, but also that the brake pedal was never applied in the final minutes before the crash.”
“The question isn’t one of mechanics and technology, but one of philosophy: if FSD is meant to be 'driving' when someone jams on the accelerator in a residential area, FSD may not be the 'driver' in one important sense, but the car was still in FSD mode.”
