How much is a child’s life worth? Probably more than $500, right? Well, new legislation requiring backup cameras on all future cars and trucks could save countless lives.

The roughly $500 camera system would make it easier to detect children, pets and pedestrians that would otherwise go unseen by rearview mirrors. That’s less money than a trip to the doctor, or even a trip to the vet. It’s also cheaper than paying for bodywork after backing into a telephone pole.

The government is currently reviewing the rules, however many automakers are already using these cameras in their new models – luxury cars and affordable cars alike.
