That's kind of the whole point. If a decision or policy has predictable consequences that aren't being addressed, either the decision-maker is unaware of those consequences or is accepting of those consequences. Asking the question removes ignorance as a possibility, and lets the conversation continue.

Sometimes the answer is "No, I was unaware, and I will adjust my decision." Sometimes the answer is "Yes, here are the consequences of the alternatives, and here's why I believe this set of consequences to be best." Sometimes the answer is "Yes, I don't care about those people." By asking the question, these three types of answers respectively give the other person an opportunity to improve themselves, give you an opportunity to learn from the other person, or give the audience an opportunity to learn not to trust the other person.

You missed one option; "You're falling prey to the is-ought fallacy." That is, saying that something is true is not the same as saying that something should be true. The original claim was that from the perspective of management at a company, 1,000 accidents the company is legally liable for is worse than 100,000 it isn't. Which is true! From that limited perspective! The reply "so you're saying it's ok that..." implies that the comment agreed with that perspective, which isn't necessarily the case. It could simply be pointing out a failure state of current management practices and corporate law. But further than that, that phrase is usually a particularly uncharitable one, and I find this usage of it to be more common than any other. I think "implying the speaker believes that the unfortunate condition they pointed out is right and just" is the normal use case for that phrase, rather than trying to bring attention to the consequences of a policy.

I think I'd put that as a subcategory of the second case, that the options were considered and this one was considered the best. That may mean that it is the least worst of several bad options, or that there are restricted options to choose from.

> Which is true! From that limited perspective! ... It could simply be pointing out a failure state of current management practices and corporate law.

I definitely agree, this is a fantastic example of options having been considered and rejected. In this case, the alternative would be "A self-driving car company accepts more liability than they can handle, and go bankrupt. This saves lives in the short-term, but costs lives in the long-term." It can then be the start of an entirely different conversation of how to avoid that failure state, and what would need to change in order to still get the benefits of that decision.

> The reply "so you're saying it's ok that..." implies that the comment agreed with that perspective, which isn't necessarily the case.

I'd make a distinction between a comment agreeing with a perspective and a commenter agreeing with a perspective. One is based solely on the text as it is written, and the other is a human's internal belief. It's not necessarily a statement that the person is wrong, but that the words they have spoken may have unintended consequences. The difference between "So you're saying $IDEA." and "So you believe $IDEA."

> I think "implying the speaker believes that the unfortunate condition they pointed out is right and just" is the normal use case for that phrase, rather than trying to bring attention to the consequences of a policy.

Good point. In situations where there are no long-term social relationships to be maintained, and where there isn't a good chance for a reply, the message given to the audience is the only one remaining. This is a major issue I have with any social group beyond a few dozen people, and one that I don't have any good solutions for.

Frequently true but rarely admitted
