First of all I think it is good that you use NASA as a way to talk about safety critical system standard. I think the common industry application is actually based upon certain variation of IEC 61508 due to it being general in nature but there is certain safety standards for different industry.
Second in terms of SIL level the introduction of AI is considered a breach of it. Therefore the use of AI is labeled to be "experimental" aka you do it your own risk that you might die or injured you. My professor always joked on it that as a safety critical guy. He would never a ride in a self driving car because you can never quantify or justify that it will work as intended due to nature of software is unpredictable. What you can do is to based on the probability of failure in the hardware which there is a expected graph of how a it will lead to failure overtime.
3rdly the whole purpose of safety critical system is to prevent the lost of life or detrimental physically harm to a human or equivalent to it. This is justified by the cost of a human life is about 1 million USD. Which is why the higher a SIL compliance the more expensive it become to build that piece of software to comply with the standard. Which is why you only do it because you want to enter or sell it to certain market or country that adopts that safety critical standard.
Depending on depending on the nature of industry, a higher failure rate is allowed like for medical devices.
I'm a small business programmer. I love solving tough problems with Python and PHP. If you like what you're seeing, you should probably follow me here on dev.to and then checkout my blog.
I used NASA's standard because anyone can look at it for free, which is not the case for IEC 61508 or ISO 26262.
I have no idea how these ML/AI systems are being installed, certified, and sold in cars as safe. My best friend was nearly killed twice in one day by one of these systems. In the first case his car veered into oncoming traffic. And in the second case the adaptive cruise control would have driven him right into the car in front of him had he not intervened and turned it off.
He pulled over and found snow had collected in front of the sensors. The car didn't warn him about questionable sensor reading, or refuse to engage those features. It just executed its algorithm assuming the sensors were correct. Not very safe behavior in my opinion.
Good point about the cost of saving one life. I've read it's different from industry to industry and from country to country. I believe nuclear and avionics in the US put the highest value on a life in the data I saw.

Ahhh... now I understand the why you choose it. Since a module of mine is based on that particular standard in my university. Plus it's really a niche subject that my professor shared to the class. He has to go to China or Singapore from time to time to teach due to the lack of it. Despite its really important especially you are implementing in the area you had mentioned.
As much as I want to have a self driving car to fetch me to move from point A to point B. Till now I'm in the same thinking as my professor of having to drive it myself or grab a taxi.

All good points.
