A new car built by my company leaves somewhere travelling at 60 mph. The rear differential locks up. The car crashes and burns with everyone trapped inside. Now, should we initiate a recall? Take the number of vehicles in the field, A, multiply by the probable rate of failure, B, multiply by the average out-of-court settlement, C. A times B times C equals X. If X is less than the cost of a recall, we don't do one.

The pinto wasn't any worse that other cars from that time period. It should come as no shock that older products are worse than newer products.
