Not according to the law though. If these "L5 cars" are obstructing traffic on the regular there's going to be a big problem. And generally, this wouldn't be L5 driving.

If it pulls over and stops in situations where a typical human could keep going safely, that's L4.

Stopping or slowing down isn’t always a “safe state”. Stopping in some situations (like on a highway) is the opposite of harmless.
