All cars inherently kill people, we should focus on the cars that kill many people in predictable ways rather than the cars that kill few people in surprising ways.

No, because some killing is necessary for the economy to function. Reduction to zero means elimination of the product.

The way this statistical background of economic death is handled is by assigning a finite value to a human life. In the US it's about $12M. If you think this is inhumane, consider that this is the cutoff for government actions for reducing deaths (from traffic accidents, disease, etc.) Actions where the cost per life saved are higher than this figure mean we're leaving on the table actions that could have saved more lives for the resources spent.
