WEST PALM BEACH, Fla. - What is already under your hood, could help detail a crash. Event data recorders are already built into most cars.
"It can actually see what you're doing when something happened, whether you were braking, or how hard you applied your brakes. They're trying to get a lot more information, like on an airplane," says GT Auto Repair owner Tom Scorza.
Now the National Highway Traffic Safety Administration wants to make the recorders mandatory on all new cars. Scorza says that's cause for concern.
"I'm a little leery about them being able to do everything today, they do enough as it is. They're really sophisticated and they're fast, and there's a lot of information in there," says Scorza.
When it comes to investigations the 'little black box' could help solve crimes. There are few leads in a recent deadly hit and run in suburban Lake Worth. Marlon Javier Padilla, 45, was run over and left for dead.
"How are you going to leave a body there, out of nowhere. You have to get out and help, obviously the gun panicked," says Brian Moran, Padilla's cousin.
If police find a suspect, they could verify what happened through the crash data. Scorza admits the positives may outweigh the negatives.
For hit and runs or red light runners, or even DUI's, absolutely because they're doing something wrong," says Scorza.
Some privacy experts say drivers should have the option to turn event data recorders off. They could be required on all new cars as early as next year.
