Level 2 Autonomous vehicles, as defined by the Society of Automotive Engineers (SAE), provide partial automation of driving functions. Level 2 Autonomous vehicles require “the driving mode-specific execution by one or more driver assistance systems of both steering and acceleration/deceleration.” For example, a vehicle with both adaptive cruise control and lane-keeping assistance would qualify as Level 2 Autonomous because the vehicle executes both acceleration and deceleration and some steering inputs. See also Level 0 Autonomous, Level 1 Autonomous, Level 3 Autonomous, Level 4 Autonomous, and Level 5 Autonomous.
