Deciphering the levels of automated driving
The SAE Levels of Driving Automation have been a standard that automakers and tech providers use to describe and categorize the capabilities and limitations of automated driving systems. They help clarify who or what is responsible for driving at a given time. Here are those levels and examples of some systems.
Level 0: A human is driving at all times. Features are limited to warnings and momentary active assistance, such as automated emergency braking. Level 1: A human is driving at all times.
