Tesla Autopilot is a suite of advanced driver-assistance system features offered by Tesla that has lane centering, adaptive cruise control, self-parking, automatic lane changes, semi-autonomous navigation on limited access freeways, and the ability to summon the car from a garage or parking spot. In all of these features, the driver is responsible and the car requires constant supervision. The company claims the features reduce accidents caused by driver negligence and fatigue from long-term driving.[1][2][3]
