Tesla wants to keep secret its response in Autopilot probe

DETROIT (AP) — Tesla wants to keep secret its response to the U.S. government’s request for information in an investigation of its Autopilot partially automated driving system. The electric vehicle maker sent a partial response by a Friday deadline to the National Highway Traffic Safety Administration, which is investigating how the system detects and responds to emergency vehicles parked on highways. In a document posted on its website Monday, the agency says it is reviewing the response and that Tesla has asked that its whole submission be treated as confidential business information. Companies often ask that some information be kept confidential when they respond to the agency. Much of the time the documents are heavily redacted before being placed in public files.
