GM Robotaxi Unit Under California Scrutiny Over Launch Readiness

A California regulator responsible for issuing driverless-car permits said it is looking into concerns raised in an anonymous letter that General Motors Cruise LLC unit was preparing to launch its robotaxi service prematurely.

The California Public Utilities Commission said it had received an anonymous letter in mid-May from a person who said he had been working at the self-driving car company for a number of years.
