It depends on what kind of error it produces.

If the error rate is only 0.5% but the death rate of those errors is 100% I am not sure it will be justifiable.

Even if the death rate is low but the _perceived_ impact is high.

Ex: Imagine a week where self-driving cars have a bug that only mis-identifies grandmas. Only a few grandmas die but the perceptual impact is massive.
