No reasonable person wants an SUV to roll over or a gas tank to explode either, but auto manufacturers calculate the cost of reducing that risk with the cost of a civil lawsuit all the time. Take the airline industry, again, for example. They could install anti-missle defenses on every commercial jet, which would subtantially reduce the chances of a plane being shot out of the sky. Why then haven't they done it? I suspect the reason is the result of risk analysis: The likelihood of the event vs. the cost of significantly reducing that likelihood vs. the economic impact to the business in the event nothing is done and the event happens.
