WASHINGTON (Reuters) - A driver killed on May 7 in a crash in a Tesla using the car's Autopilot software was speeding, the U.S. National Transportation Safety Board said on Tuesday in its preliminary findings. The preliminary report said the Model S was traveling at 74 miles per hour in a 65 mph zone at the time it struck a semi-truck hauling blueberries near Williston, Florida. The report said the NTSB confirmed the Model S driver was using the advanced driver assistance features Traffic-Aware Cruise Control and Autosteer lane-keeping assistance at the time. The NTSB has not yet determined the probable cause for the crash. (Reporting by David Shepardson; Editing by James Dalgleish)
