WASHINGTON—The U.S. National Transportation Safety Board said on Sunday it was “unhappy” that electric car maker Tesla Inc made public information about the crash of its Model X vehicle on Autopilot that killed the driver last month.
The agency “needs the cooperation of Tesla to decode the data the vehicle recorded,” NTSB spokesman Chris O'Neil said in a statement. “In each of our investigations involving a Tesla vehicle, Tesla has been extremely cooperative on assisting with the vehicle data.”
