Well there's really only two options for a self driving car that has lost situational awareness - (1) keep going at the same speed, or (2) slow down and alert the driver (and possibly stop if the driver doesn't respond).
Choeger was suggesting that (2) was the prudent option. You replied and appeared to be suggesting the first option because slowing down was dangerous. But I contend that (1) is the more dangerous option if situational awareness has been lost.
Like handing control back to the human, it depends on the timescale. Over longer periods, yes, obviously the only sane option is to stop. But if confidence in sensors or analysis suddenly drops, especially when the system is still under development and unknowns are expected, the response needs to be graceful rather than sudden.
This is reflected in their comment generally, but talks past the context of my comment. In the scenario I'm envisioning, most of the view is fine right up until say the last ten seconds, where the dynamic range of the camera is suddenly overloaded. That's not enough time to talk about stopping or handing off control, and slowing down isn't going to help with the automation having lost the lane. A human gets through the situation by making a plan ahead of time, including taking note of how a road curves and guessing that the lane will remain clear. Whereas I can imagine automation responding in a horribly wrong way.
