Levels of Autonomy

The Society of Automotive Engineers (SAE) has established a classification system that defines six levels of vehicle autonomy, ranging from Level 0 (no automation) to Level 5 (full automation). Understanding these levels is essential for grasping the current state of autonomous vehicles.

Level 0: There is no automation; the human driver is responsible for all aspects of driving.
Level 1: Driver assistance: The vehicle can assist with steering and acceleration/deceleration, but it requires constant human oversight.
Level 2: Partial Automation: Under certain conditions, the vehicle can control both steering and acceleration/deceleration simultaneously, but the driver must remain engaged.
Level 3: Conditional automation; the vehicle can handle most driving tasks independently, but the driver must be ready to intervene if necessary.
Level 4: High automation: The vehicle can operate independently in specific conditions without human intervention, but it may require a driver in complex scenarios.
Level 5: Full automation; the vehicle can operate independently in all conditions without any human intervention.

The current state of autonomous vehicles

As of now, most commercially available vehicles with autonomous features fall between Level 2 and Level 3. Tesla's Autopilot and General Motors' Super Cruise are examples of Level 2 systems that provide advanced driver assistance. We are still in the testing phase and have not yet widely deployed fully autonomous vehicles (Level 5).
