WASHINGTON—The chairman of the U.S. National Transportation Safety Board (NTSB) on Nov. 19 criticized Uber Technologies Inc. for its “ineffective safety culture” at the time of a March 2018 fatal self-driving car crash in Arizona.
NTSB Chairman Robert Sumwalt said “the inappropriate actions of both the automatic driving system as implemented and the vehicle’s human operator were symptoms of a deeper problem” citing the “ineffective safety culture that existed at the time of Uber.”
