The NHTSA has been pushing for mandatory backup cameras on all vehicles from some time now, in order to prevent the deaths of children who like to nap behind cars. While saving childrens' lives is, of course, a noble aim the fly in the ointment is the $2.7 Billion cost of installing backup cameras, and screens to go with them, in every new car. Given how few accidents would be prevented by this (around 150 per year), many are saying that amount of money could be more effectively spent, and save more live, by investing in other safety equipment.
As a result of the cost and the controversy, the NHTSA has pushed the mandate back to 2015 from 2014.
