It also relies on whomever is modeling the reductive, simplistic "cost model" to know the effect of all the other variables that factor into the companies success. Do these people really think that the legal/compensation costs are the only effect? How many sales did Ford miss out on because they were labeled as the "There is a known issue in this car that might kill you but until your life is worth more than a replacement part we wont repair it" car company? Did they factor in those costs into their revenue model projections? Did they factor in the sag in price point demand "Boss I wouldn't bid the same on that contract because they've shown themselves to sell a known defective product and we'll open ourselves to legal issues if one of their cars kill one of our customers we're transporting in their vehicles"

There will always be things you can do that increase safety at a cost, but some of them will necessarily not be worth the effort, or you're forced to spend without bound on ever-more safety to the point that it's not worth using (and which may push people into still-riskier alternatives).

If you're turning down a company for making such a tradeoff, that's like saying "I'll buy a Ford rather than a GM because people might die in GMs."
You're right that you can legitimately criticize a company for failing to include certain things as costs, but it's not fair to fault them for somehow making this inevitable tradeoff, especially in the belief that you have some alternative provider that isn't.
(And example of such a cost -- that they can legitimately be expected to but don't -- would be something like "impact on general perception of risk", "impact on reputation of the car industry".)

It sounds more like you're agreeing that it's that simple, but that Z (events worthy of consideration) is not as simple as in typical models.
