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, as well as preventing the car from wandering off the road. Model S can also scan for a parking space, alert you when one is available, and parallel park on command. Autopilot features are progressively enabled over time with software updates.
