Ford Pinto
The cases involving the explosion of Ford Pinto's due to a defective fuel system design led to the debate of many issues, most centering around the use by Ford of a cost-benefit analysis and the ethics surrounding its decision not to upgrade the fuel system based on this analysis.
The Ford Motor Company contended that by strictly following the typical approach to risk,/benefit analysis, they were justified in not making the production change to the Pinto model. Assuming the numbers employed in their analysis were correct, Ford seemed to be justified.
The estimated cost for the production change was $11 per vehicle. This $11 per unit cost applied to 11 million cars and 1.5 million trucks results in an overall cost of $137 million.
The controversial numbers were those Ford used for the "benefit" half of the equation.
It was estimated that making the change would result in a total of 180 less burn deaths, 180 less serious burn injuries, and 2,100 less burned vehicles. These estimates were multiplied by the unit cost figured by the National Highway Traffic Safety Administration. These figures were $200,000 per death, $67,000 per injury, and $700 per vehicle equating to the total "societal benefit" is $49.5 million. Since the benefit of $49.5 million was much less than the cost of $137 million, Ford felt justified in its decision not to alter the product design. The risk,/benefit results indicate that it is acceptable for 180 people to die and 180 people to burn if it costs $11 per vehicle to prevent such casualty rates. On a case by case basis, the argument seems unjustifiable, but looking at the bigger picture complicates the issue and strengthens the risk/benefit analysis logic.
