The document discusses Ford's development of the Pinto model in the 1970s. Testing found safety defects where the gas tank could rupture in rear-end collisions. Fixing the defect would cost $11 per vehicle. Alternatives were considered, including adding a rubber bladder for $5.08 per vehicle. The recommendation was to explore other safety measures to repair the Pinto in a cost-effective way and avoid exposing customers to unknown risks.
