Airbags in cars are a good thing, right? They save lives. The U.S. National Highway Safety Administration estimates that out of over three million airbag deployments from 1990 to 2000, some sixty-four hundred lives have been saved by the little poofy pushback pillows. And they figure countless injuries have been prevented. So all good, right? Airbags are the greatest invention since the waffle iron, or lip gloss, or monkey bars.
