U.S. automobile safety regulators are closing their preliminary investigation into General Motors’ Cruise robotaxis without taking further action

US auto safety regulators ended a federal investigation into Cruise robotaxis without taking action, removing an overhang weeks after General Motors Co. decided to shutter the struggling business.

The National Highway Traffic Safety Administration’s Office of Defects Investigation has closed their preliminary investigation into General Motors' ( NYSE: GM) Cruise division and will take no further action. The agency noted the company’s decision to end robotaxi development.

The agency said it analyzed 2,759 reports identified by Cruise that involved collisions, including 1,113 that involved a “pedestrian conflict.”
