Once again, the federal mandate for backup cameras has been delayed. According to Automotive News, the rule requiring backup cameras in new cars is being pushed back to 2015, reportedly because regulators are now considering giving safety rating incentives to vehicles equipped with this new technology.

US Transportation Secretary Ray LaHood, who will be stepping down from his role once a successor is confirmed, said that more analysis of the rule's cost to the auto industry as a whole is necessary before the mandate is officially issued, Automotive News reports. NHTSA has said that that the cost would be roughly $2.7 billion, or as much as $18 million per life saved.

The National Highway Traffic Safety Administration delayed its backup camera rules earlier this year (on top of several other setbacks), even though the original plan was to require automakers to outfit at least 10 percent of their cars with this technology by 2012. From there, that number was scheduled to rise to 40 percent by 2013 and 100 percent by 2014.
