It was the most recent twist in a saga that has disrupted typical automotive business practices and drawn the eye of security advocates and regulators, who worry the implications of Tesla foisting the largely untested software on the general public. Full Self-Driving is an expanded iteration of the software that Tesla calls Autopilot, which may navigate highways, summon and park vehicles, and conduct different maneuvers with an attentive driver behind the wheel. Full Self-Driving brings these capabilities to metropolis streets, permitting the software to navigate Tesla vehicles by way of native roads and residential areas. Users should listen always, and the software — regardless of its identify — is not thought-about autonomous by business or regulatory definitions.
