>“Whether a [Level 2] automated driving system is engaged or not, every available vehicle requires the human driver to be in control at all times, and all state laws hold the human driver responsible for the operation of their vehicles,” a NHTSA spokesperson said.

This is going to be the interesting part. To my mind this is where partial automated driving systems are basically incompatible with people and cars. There is just no way a person who is behind the wheel but who isn't driving can be in control and highly attentive in the same way as a person who is actually driving.
