Federal regulators have launched an investigation into Tesla's new taxis. The National Highway Traffic Safety Administration is looking into whether these vehicles comply with safety rules. The taxis in question lack steering wheels, mirrors, and brake pedals, which are typically required in vehicles.

The investigation began a day after Tesla started offering rides in the taxis. The company's leader, Elon Musk, had kicked off the service with an event. Further details about the investigation and the taxis are available from the source, including the impact on Tesla's stock price.
