Federal regulators have opened yet another investigation into Tesla’s so-called full-self driving technology after dozens of incidents in which the electric vehicle maker’s cars ran red lights or drove on the wrong side of the road, sometimes crashing into other vehicles and endangering drivers. The National Highway Traffic Safety Administration said in a filing dated Tuesday that it has 58 incident reports of Tesla vehicles violating traffic safety laws while operating in full self-driving mode. In reports to regulators, many of the Tesla drivers said the cars gave them no warning about the unexpected behavior. The probe covers 2.9 million vehicles, essentially all Teslas equipped with full self-driving technology
