“NHTSA is concerned that this feature was introduced to consumer vehicles, and now that the existence of this feature is known to the public, more drivers may attempt to activate it,” John Donaldson, the agency’s acting chief counsel, wrote in a July 26 letter to Tesla that was posted Wednesday on the agency’s website.
The special order tells Tesla to describe differences in the software update that reduces or eliminates instances where Autopilot tells drivers to apply pressure on the steering wheel, “including the amount of time that Autopilot is allowed to operate without prompting torque, and any warnings or chimes that are presented to the driver.”
