WASHINGTON, Nov 8 (Reuters) - The National Highway

Traffic Safety Administration raised concerns about Tesla

social media posts that suggested its Full Self-Driving

software can be used as a robotaxi and do not need driver

attention.

NHTSA in October opened an investigation into 2.4 million

Tesla vehicles with FSD software after four reported collisions,

including a 2023 fatal crash. In a May 14 email made public

Friday, NHTSA told Tesla its social media postings could

encourage people to see FSD as a robotaxi "rather than a partial

automation/driver assist system that requires persistent

attention and intermittent intervention by the driver."
