Speaking as somebody who has chronic kidney disease but is very much not dead (last I checked), I feel compelled to point out that the car analogy omits the vast majority of the people impacted, many of whom will have lifelong battles with cardiovascular health and increased risk of serious illnesses (e.g. gout). Kidney damage is permanent and irreversible. Renal tissue does not regenerate.

Just because only six babies died from acute kidney damage (according to the article you linked, which does not quite agree with your numbers) does not mean that's where the damage ends. Evidently there were 54,000 babies who were impacted severely enough to be hospitalized -- that's 18%, a far cry from 0.001%, and most definitely not an indication that an ingredient is "almost safe". Ignoring 53,997 of them makes your analogy incomplete to the point of being specious.
