The head of the National Transportation Safety Board expressed concern about the safety risks that heavy electric vehicles pose if they collide with lighter vehicles.
FILE - Jennifer Homendy of the National Transportation Safety Board speaks during a news conference, Oct. 3, 2019, in Windsor Locks, Conn. On Wednesday, Jan. 11, 2023, Homendy, the chairwoman of the National Transportation Safety Board, said she is concerned about the risk that heavy electric vehicles pose if they collide with lighter vehicles.
The extra weight that EVs typically carry stems from the outsize mass of their batteries. To achieve 300 or more miles of range per charge from an EV, batteries have to weigh thousands of pounds. “We have to be careful that we aren’t also creating unintended consequences: More death on our roads,” she said. “Safety, especially when it comes to new transportation policies and new technologies, cannot be overlooked.”
Michael Brooks, executive director of the nonprofit Center for Auto Safety, said he, too, is concerned about the weight of EVs because buyers seem to be demanding a range of 300 or more miles per charge, requiring heavy batteries. Brooks said he knows of little research done on the safety risks of increasing vehicle weights. In 2011, the National Bureau of Economic Research published a paper that said being hit by a vehicle with an added 1,000 pounds increases by 47% the probability of being killed in a crash.
