According to reports from Chicago’s ABC7 and ABC25 in West Palm Beach, Fla., a car driven by 57-year-old Cathy Bernstein automatically called 911 to report a crash. The call was part of a safety feature designed to help first responders locate people who may have lost consciousness in crashes. That seems to have given dispatchers all the information they needed to pinpoint the location of the vehicle — and find the alleged hit-and-run driver — without ever having to talk to a person. In fact, talking to a person didn’t help at all: in an audio clip of a 911 call obtained by the Florida station, Bernstein denied to a skeptical dispatcher that there even been any accident at all.

The report said the car that tattled on its owner was a Ford; Police in Port St. Lucie, Fla., did not immediately respond to a request for comment.
