L3 requires zero attention, that’s what makes it L3 vs L2. The driver needs to stay sober, awake, and in the drivers seat but are supposed to be able to read a book or something.
A L3 car is required to be able to handle all short term situations and only do a handoff with 5-10 seconds of warning. The idea is it’s ok for the car to come to a complete stop and say I have no idea what to do, but it isn’t ok to simply fail on a freeway at 70 MPH.
Failing safely is a huge difference, as mentioned in the article: if a driver doesn't take over when prompted the car activates the hazard lights and slowly comes to a stop before making an emergency system call to alert first responders to a potential problem.
