The head of the National Transportation Safety Board expressed concern Wednesday about the safety risks that heavy electric vehicles pose if they collide with lighter vehicles.
Homendy said she was encouraged by the Biden administration’s plans to phase out carbon emissions from vehicles to deal with the climate crisis. But she said she still worries about safety risks resulting from a proliferation of EVs on roads ands highways.
Homendy noted that Ford’s F-150 Lightning EV pickup is 2,000 to 3,000 pounds heavier than the same model’s combustion version. The Mustang Mach E electric SUV and the Volvo XC40 EV, she said, are roughly 33% heavier than their gasoline counterparts.The NTSB investigates transportation crashes but has no authority to make regulations. For vehicles, such authority rests largely with the National Highway Traffic Safety Administration.
Setting up a charging network to accommodate that may be a mistake from a safety perspective, Brooks said.“These bigger, heavier batteries are going to cause more damage,” he said. “It’s a simple matter of mass and speed.” He points out that electric vehicles have very high horsepower ratings, allowing them to accelerate quickly even in crowded urban areas. “People are not trained to handle that type of acceleration. It’s just not something that drivers are used to doing,” Brooks said.
