GM’s self-driving car subsidiary Cruise said earlier this year that it wants to add as many as 5,000 more robotaxis to American streets, including in San Francisco, where it currently maintains a fleet of fewer than 100 cars…

Cruise requested approval for a new vehicle that could vastly expand the size of its San Francisco-based fleet – as much as 50 times the size – as it strives to reach $1 billion in revenue before 2025.

But San Francisco has concerns ranging from general traffic to dangerous situations that have already been encountered, the city said in a 36-page response, filed last week as part of a request for public comment issued by the National Highway Traffic Safety Administration (or NHTSA) in response to GM’s request to be exempted from some federal safety standards for its new self-driving vehicle, known as the Cruise Origin.
