Question 1) Is there something unethical about using cost-benefit analysis?

Question 2) As a society we often perform cost-benefit analyses involving lives. For example, we do not require overpasses to be built at all railroad crossings, even though we know that an occasional fatal collision will occur if we do not. How is this different from what Ford did?

Question 3) Could it have been possible that upper management at Ford did not understand the engineering issues involved? (What was Lee Iacocca's technical background?)

Question 4) Suppose you were an engineer at Ford and you have just discovered the Pinto's gas tank problems. You discuss the situation with your manager and he tells you he doesn't see a problem. What, if anything, do you do next?

Provide thorough explanation of the given question.
