The signal is clear enough at a safe speed, but there wasn't much time to react zooming around inside a cloud.
Really? I wouldn't have missed. There was plenty of time for the car to stop based on the video I saw. It looks like 4 seconds of visibility before the driver had to turn the car. It didn't seem like the car was going that fast. There's no way a normal human being paying attention wouldn't be able to get the car to a full stop in that 4 seconds.
From what I understand, Tesla's FSD only uses vision to drive. But we, as humans, use all of our senses to drive. We use vision, smell, sound, as well reasoning and historical knowledge.
If I saw flashing lights in a fog, I would slow down no matter what. I might have heard some sounds, however faint, from the train moving. I would have reasoned that I should always drive slow in the fog, particularly near an area where there are train tracks. I might have sensed that we are driving in train track territory because I saw some tracks around here in the past or I have come across knowledge about this area before that I remembered. Tesla's FSD uses non of these senses.
If I see a crashed oil truck and there is a strong gasoline smell, I might drive as fast as possible out of the way in case it explodes or catches fire. If I smell something weird coming from the car's components, I might stop and not drive. If I smell a cow poop (such as near UC Davis), I might ready by brain for the tiny chance that a cow might escape the fence into the road.
We don't just use pure vision like FSD. If FSD is only vision, then it should make up for the other senses such as sound, smell, and human reasoning with things that humans don't have such as rador/lidar.

If anything, you need a modern car with HEPA filter (i.e. like most Teslas)...
