Tesla shares slump 6% after feds launch probe into new Cybercabs without steering wheels

Tesla began commercial deployment of a small number of the two-seater Cybercab, with plans to gradually expand the service to additional vehicles and locations. While the rollout is initially limited, the staged expansion suggests progress from pilot to scale, which is supportive for the autonomy/robo-taxi roadmap. Market impact is likely modest near term given the small initial fleet.
