SAN JOSE, Calif. – A proposed mandate from the U.S. Department of Transportation will cause sales of new cars with rear-view park assist cameras in the country to quadruple, according to iSuppli, now part of IHS Inc.

”The mandate calls for all new motor vehicles weighing less than 10,000 pounds sold in the United States to incorporate backup cameras by Sept. 1, 2014. The cameras are designed to eliminate blind spots behind cars that contribute to backover collisions,” according to iSuppli.

”Because of this, all new cars sold in model year 2015 are expected to include rear-view park assist cameras, up from iSuppli’s previous forecast of only 20 percent,” according to iSuppli.

ISuppli now projects that from 2011 through 2017, 71.2 million new cars in the United States will be sold with rear-view cameras for park assistance. The pre-mandate forecast predicted only 19.1 million for the same period.

With the U.S. market beginning to accelerate dramatically in 2012, sales will rise 119.9 percent to 2.8 million units, up from 1.3 million units in 2011. Sales then will increase by 117.4 percent in 2013 to reach 5.98 million, and will climb another 91.1 percent in 2014 to hit 11.4 million. By 2017, a total of 17.1 million cars, representing the entire estimated new-vehicle fleet, will be sold with rear-view cameras in the United States.

However, there is a down side. ”The rollout of rear-view camera technology on the massive U.S. automotive fleet will be costly. NHTSA estimates that a rear-view camera system will cost from $159 to $203 when installed on a vehicle without an existing display,” according to the report.
