Black boxes spark uproar.

WASHINGTON - A new federal rule to standardize minimum requirements for "black boxes" in vehicles wasn't expected to be controversial, but it has ignited a firestorm of protests from groups that largely agree the information collected by the devices improves auto safety. All U.S. and foreign automakers have asked the National Highway Traffic Safety Administration to rewrite the rule because they say it's too vague and will cost too much to implement. Safety advocates say it doesn't go far enough.
