A mannequin simulating a child crossing the street to board a school bus was crushed over and over again by a Tesla equipped with a self-driving feature on Thursday—safety advocates' latest warning of weaknesses in the automaker's tech as it prepares to launch robotaxis on Austin roads.

Though the test was completed with child-sized manikins as opposed to real children, the Tesla failed the test all six times.

With Tesla just days away from a planned rollout of its paid robotaxi service in Austin, the electric vehicle manufacturer is reportedly trying to prevent city officials from releasing records related to its robotaxi trial period.
