There are plenty of medical procedures that save lots of lives but occasionally kill people. The public is ok with that because it is way better than the alternative.
Medicine generally is the closest analog. On the other hand when someone dies because of a rare drug side effect, lawsuits are common. There's a reason why the drug companies are protected from liability in the case of common vaccines [and that medical malpractice insurance is so expensive].
Except in this case, someone else's bad medicine can kill you.
Yes but usually those medical procedures prove that they save more people than they kill before they're given to the public. Self-driving cars have not done that.
