WASHINGTON (AP) — Elon Musk has long railed against the U.S. government, saying numerous investigations and safety programs have stymied Tesla, his electric car company, and its efforts to create fleets of robotaxis and other self-driving automobiles. Now, Musk’s close relationship with President Donald Trump means many of those headaches could vanish. On the potential chopping block: crash investigations into Tesla’s partially automated vehicles; a Justice Department criminal probe examining whether Musk and Tesla overstated their cars’ self-driving capabilities; and a government mandate to report crash data on vehicles using technology like Tesla’s Autopilot. The consequences of such actions could prove dire, say safety advocates who credit the investigations and recalls with saving lives.
