> Levels 3-5 are considered Automated Driving Systems (ADSs) in which the driver does not need to pay attention to the road.

I'm going to say that's patently wrong.

as the article points out at level 3, the control system is likely to drop out and punt hard decisions over to the driver at any time. This is exceptionally dangerous because there is almost never enough time to react properly (unless the driver was actively paying attention)

at level 3 you really still need to pay attention.
