And now an announcement fueled by a great fear in all american families. You back up in the driveway unaware that a child is behind you in the blind spot. Well, tonight the government has a new recommendation on american cars, but critics are saying the stakes are so high that merely recommending action is not enough. Here's abc's david kerley. Look back, ready to go. Reporter: It's a powerful image of how little we can see in our car mirrors. But wait. Reporter:62 children, unseen and vulnerable, behind the car. The reason parents who have run over their own children are demanding back up cameras in every car. Mommy, mommy, you hit me with the car. Why did you hit me with a car? I didn't see you. Reporter: Tonight, susan aureimma is part of a lawsuit against the obama administration, demanding it do what congress ordered in 2007. Come up with a rule for back-up cameras and cars. Last night the government announced it will add review veer cameras not as a rule but a recommended feature in new cars. It's too little too late. The sooner we can issue this regulation, the sooner we can stop it. Reporter: Her daughter survived but 15 thousands people are injured every year. Already more than half of new cars do have back-up detection and it works. Here's the problem. Even if you look behind your car and check your mirrors you still may not see a child. That's why these auto braking systems or cameras can help save a life. 2 to $4,000 as part of a safety package, a small price to avoid a deadly mistake. David kerley, abc news, washington.
