Food and Drug Administration The FDA oversees the clinical trials for Neuralink, Mr. Musk's brain implant company, deciding whether such trials can take place and whether Neuralink can eventually sell its device to consumers. The agency already approved such trials in the U.S. Neuralink has also been pursuing clinical trials outside the U.S, including in Canada. The FDA had initially rejected Neuralink's request to start clinical trials, citing safety risks, Reuters reported in 2023. The agency has since given the startup approval to do clinical trials, which are ongoing. Environmental Protection Agency SpaceX faces environmental regulations from the EPA, which oversees the company's wastewater discharges at its operating site in Texas. The company's operations are also subject to environmental reviews under the National Environmental Policy Act, with several agencies including the Fish and Wildlife Service required to analyze the impact of the company's rocket launches and landings on land, water and wildlife. National Highway Traffic Safety Administration Tesla faces ongoing oversight from U.S. auto safety investigators about the safety of its vehicles especially when using advanced driver assistance systems. Last month, the National Highway Traffic Safety Administration asked Tesla to answer questions on its plans to launch a paid robotaxi service in Austin, Texas, in June, in order to assess how the electric vehicle maker's cars with full self-driving technology will perform in poor weather. NHTSA has been investigating Tesla's full self-driving collisions in reduced roadway visibility conditions since October. The agency said it is seeking additional information about Tesla’s development of robotaxis "to assess the ability of Tesla’s system to react appropriately to reduced roadway visibility conditions" as well details on robotaxi deployment plans and the technology being used.
