In closing the probe, NHTSA cited Cruise’s decision to recall its driving system software and noted that the company has since ceased operating on public roads. The agency said in a document posted to its website on Jan. 15 that it “reserves the right to take additional action if warranted by new circumstances.”
GM didn’t immediately respond to a request for comment.
The announcement comes about a month after GM said it would shut down the robotaxi operations, citing heavy development costs. The automaker said it would fold Cruise into its existing business and continue to pursue driverless technology for future models.
