SAE level 2 is just a bad idea. People can't be expected to carefully monitor a car and take over at a moment's notice when it's doing all the driving. My adaptive cruise control is great and I hope to have a future car where I can zone out while it drives and take over after after a few seconds heads up, but the zone between shouldn't be a valid feature.
I think you mean SAE Level 3. SAE Level 2 is “lane centering” and “adaptive cruise control” [1]. (Level 3 is “when the feature requests, you must drive.)
