Some of the vehicle safety features that we now take for granted have not been around all that long. It is difficult to imagine driving a car without seat belts or air bags. But after each was invented, there was a period of time in which they were optional "luxury" items that customers had to pay more money for.
Such is the power of government regulation. Today, there is no question that new vehicles must come with seatbelts and at least a minimum number of air bags. These safety features are simply too valuable to be considered optional add-ons. Should regulators be making similar decisions about other types of auto safety technology?
