Autopilot
Autopilot allows Model S to steer within a lane, change lanes with the simple tap of a turn signal, and manage speed by using active, traffic-aware cruise control. Digital control of motors, brakes, and steering helps avoid collisions from the front and sides, and prevents the car from wandering off the road. Autopilot also enables your car to scan for a parking space and parallel park on command. And our new Summon feature lets you "call" your car from your phone so it can come greet you at the front door in the morning.
Autopilot features are progressively enabled over time with software updates.
Automatic steering with traffic aware cruise control
Active sensors combined with GPS and high resolution digital maps comprise a mutually reinforcing system that pilots Model S along the highway, staying within your lane, even in stop and go traffic. Real time feedback from the Tesla fleet ensures the system is continually learning and improving upon itself.
