When a Tesla vehicle has this mode enabled, it eliminates what owners of the cars refer to as the "nag." The researcher has nicknamed the feature "Elon Mode," but that is not the company's internal nomenclature for it, he said. Instead, Tesla driver assistance systems require a human driver to remain attentive and ready to brake or steer at any moment. Typically, when a Tesla driver is using Autopilot or FSD (or their variations), a visual symbol blinks on the car's touchscreen to prompt drivers to apply resistance to the steering wheel at frequent intervals. If the driver does not grasp the steering wheel, the nag escalates to a beeping noise.
