Is there realistically any other way to do this though? The value of life, as estimated by a human in a generic situation is presumably infinite. However, companies, governments, regulating bodies, etc, have to regulate actual physical measures, which cost money, time etc- all very finite things. These agents need to act in actual physical environment like for example limited budgets or having to choose between two different safety measures. At some point the human life is going to have to enter that equation, if we are going to be talking about safety issues. How do you calculate en equation with finite and infinite variables without assuming a finite value for the human life?
