SAE J3016 Automation Levels are widely used, controversial -- and arguably not the right way to describe automation for anyone other than the engineers designing the systems.
In the video below I give a summary of SAE J3016 terminology and the infamous Levels and provide an alternative description approach. I also cover some of the many myths that so many people think are true, but which are not actually part of that standard at all.
I have also published a pretty thorough SAE J3016 User Guide that details more precise definitions and myths to help those who need to get things exactly right find the subtleties in the standard that are not apparent after only one (or two, or three) reads.
