US transportation regulators are investigating Tesla's new Robotaxi service in Austin, Texas, following videos showing the vehicles exceeding speed limits and making unsafe lane changes. The NHTSA is gathering information from Tesla after several influencers' videos highlighted these issues. This comes as Tesla faces scrutiny over its "Full Self-Driving" mode following a fatal accident in 2023. The launch, despite Tesla's positive promotion, has raised concerns about the safety of the technology and its compliance with traffic laws. Tesla's future heavily relies on the success of its Robotaxi program.
