General Motors startup Cruise LLC said it had recalled and updated software in 80 self-driving vehicles after a June crash in San Francisco that left two people injured.
The ruling followed days of uncertainty about Musk's intentions and removed the threat that the erratic entrepreneur would have to testify under oath this week about his claims that Twitter fraudulently misled him.
While Musk will provide much of the funding after selling down his stake in electric vehicle maker Tesla Inc and by leaning on equity financing from large investors, major banks have committed to provide $13 billion.
Following a GM petition as well as a June crash involving an autonomous vehicle, the City and County of San Francisco said in its comments GM and Cruise failed to provide sufficient data and fell "short of documenting or analyzing the safety performance" of the self-driving vehicles.
