Psst, Your Car is Watching You

Black boxes exonerate drivers too: a Fort Myers, Fla., man was acquitted of reckless speeding, despite a witness's testimony that he was traveling over 90 m.p.h., because his truck's black box registered only 60 m.p.h.

In a Nassau County, N.Y., courtroom last year, almost everyone wept when Blake Slade and Kyle Soukup were sentenced to three years in prison. The youths cried as they apologized. The families of the betrothed who died in the Muttontown crash spoke of justice and forgiveness. Even the judge dabbed his eyes and choked up.

But the prosecution and the defense remain bitterly divided over the role of the black box. Slade's father Richard calls it "a violation of civil rights," while the assistant district attorney, Michael Walsh, praises it as "the strongest piece of evidence in the case." Neither had heard of EDRs before the crash, but today both agree on one point: motorists should be aware that their cars have recorders, and it's to be hoped that the knowledge will encourage them to drive safely. "Otherwise," Slade warns, "the black box can come back to haunt you."
