Florida (again...seriously, what is it with that state?) resident Cathy Bernstein learned this the hard way. First she drove her Ford vehicle into a truck. Then she smacked it into a van. Then she took off.
Unfortunately for her, her car was equipped with Ford's Sync system - which has a feature called 911 Assist. If you're in an accident that involves airbag deployment, it automatically calls 911. Unfortunately for Bernstein, her car did exactly what it was supposed to do: It automatically called 911 after her little sheetmetal-sculpting episode.
Authorities were contacted, and when they called Bernstein back and asked her if she had left the scene of an accident, instead of fessing up, she lied, saying "no, I would never do that." She obviously never learned the don't-fib lesson in Kindergarten.
Alas, the damage was a little too hard to hide, and Bernstein was subsequently arrested for hit-and-run. Chalk up another win for technology. At this rate, hit-and-run "accidents" could be a thing of the past before long. Now wouldn't that be something?
