In road-transport terminology, lane centering, also known as auto steer or autosteer, is an advanced driver-assistance system that keeps a road vehicle centered in the lane, relieving the driver of the task of steering. Lane centering is similar to lane departure warning and lane keeping assist, but rather than warn the driver, or bouncing the car away from the lane edge, it keeps the car centered in the lane. Together with adaptive cruise control (ACC), this feature may allow unassisted driving for some length of time. It is also part of automated lane keeping systems.

Tesla Autopilot is an advanced driver-assistance system (ADAS) developed by Tesla that amounts to partial vehicle automation. Tesla provides "Base Autopilot" on all vehicles, which includes lane centering and traffic-aware cruise control. Owners may purchase an upgrade to "Enhanced Autopilot" (EA) which adds semi-autonomous navigation on limited access roadways, self-parking, and the ability to summon the car from a garage or parking spot. The company claims the features reduce accidents caused by driver negligence and fatigue from long-term driving. Collisions and deaths involving Tesla cars with Autopilot engaged have drawn the attention of the press and government agencies.
