The headline is wildly incorrect. Large vehicles are only responsible for about a 7.5% increase. Odd they aren't talking about the bigger issues at play and chose to mislead us.

“Our estimate is that about 200 to 400 pedestrians a year would not have died if vehicles had remained approximately the same size over the past quarter-century,” the report continued. “That represents about 10 percent of the recent increase in pedestrian deaths.”

"According to the report, pedestrian deaths have not only increased by 75% since 2009, but the fatalities have been correlated with the hazards presented by the physical heft, height, and blind spots inherent to today’s big trucks and SUVs."
