9 people dying in an accident is rare, but not that unusual. This can happen when a freeway ices up and a major pileup occurs. Sometimes church vans drive very slowly into places they shouldn't be and then end up overturned, sometimes in water, and often killing or injuring most of the people on board. This happens way more often than people would expect.
Meanwhile, alcohol and drugs kill more people on the road than any other set of causes. Perhaps all vehicles should just have a breathalyzer interlock as a standard option? What other measures of condescending paternalism can we implement to "save lives?"
