The US National Highway Traffic Safety Administration has contacted Tesla after reports of dangerous driving from its robotaxis were shared on social media.

The National Highway Traffic Safety Administration is seeking information from Tesla after reviewing online videos of a robotaxi allegedly using the wrong lane and of speeding by another driverless vehicle.

US auto safety regulators are looking into incidents where Tesla Inc.’s self-driving robotaxis appeared to violate traffic laws during the company’s first day offering paid rides in Austin.
