A preliminary National Transportation Safety Board (NTSB) review of the fatal Amazon "Prime Air" crash in Miami found that a pilot warned the aircraft was "too fast" before the accident. The crash killed five people and injured five others, although the NTSB did not identify which pilot issued the warnings. The week also brought a dispute between Ford Motor Co and President Donald Trump's Transportation Secretary, Sean Duffy, over the automaker's relationships with China-linked companies including CATL, Geely Automobile Holdings Ltd. and BYD Co. Ltd. Duffy cited potential U.S. security risks and expressed "profound concern" about Ford's battery and vehicle arrangements. Ford rejected the criticism, saying Duffy's letter contained factual errors about its BlueOval Battery Park Michigan and its agreement with CATL, while the company's stock traded higher. Separately, Tesla Inc. CEO Elon Musk denied that the company's Autopilot driver-assistance technology was involved in a fatal New York City crash involving a Tesla Model Y and scaffolding. Musk said the crash would not have occurred if Autopilot had been operating. Goldman Sachs estimated that Tesla's Cybercab could cost up to 30 cents per mile less than rival autonomous vehicles if Tesla reaches its targeted production costs, helped by its low-cost design and camera-only sensor system. The roundup also referenced criticism of Tesla's Cybercab launch by TSLA critic Gordon Johnson and related comments involving Elon Musk, as well as reports that Trump said the U.S. struck nine Iranian ships and that Chris Wright criticized Gavin Newsom and Joe Biden over closed refineries.
