Two U.S. senators on Thursday urged the National Highway Traffic Safety Administration (NHTSA) to reconsider its decision to tell automakers not to comply with a Massachusetts state "right to repair" law designed to allow customers access to vehicle data so they can seek repairs outside dealerships.

Senators Elizabeth Warren and Ed Markey, both Democrats of Massachusetts, in a letter to the NHTSA and U.S. Department of Transportation, said the agency's decision "to give auto manufacturers a green light to ignore state law appears to favor Big Auto."
