ERIC LAWRENCE, NATHAN BOMEY AND KRISTI TANNER :

A Detroit Free Press/USA TODAY NETWORK investigation found that the SUV revolution is the most likely cause of escalating pedestrian deaths nationwide, which are up 46 percent since 2009.
 
 Almost 6,000 pedestrians died on or along U.S. roads in 2016 alone — nearly as many Americans as have died in combat in Iraq and Afghanistan since 2002. Data analyses by the Free Press/USA TODAY and others show that SUVs are the constant in the increase and account for a steadily growing proportion of deaths.
