TESLA CAR FIRE: ABC7 investigates deadly accident on Highway 101 in Mountain View
NTSB spokesman Chris O'Neil said that while Tesla has been "extremely cooperative" in assisting with the vehicle data aspect of investigations involving their vehicles in the past, the NTSB expects parties involved in their investigations to inform them of releases before making information public.
The Tesla team posted in a blog post on Friday that in the moments before the collision, which happened on U.S. Highway 101 at 9:27 a.m. on March 23, Tesla's Autopilot system was engaged with adaptive cruise control follow-distance set to minimum.

"The driver had received several visual and one audible hands-on warning earlier in the drive and the driver's hands were not detected on the wheel for six seconds prior to the collision," the company said in their post. "The driver had about five seconds and 150 meters of unobstructed view of the concrete divider with the crushed crash attenuator, but the vehicle logs show that no action was taken."
Tesla had previously stated that the crash was made worse, fatally killing driver Wei Huang of San Mateo, because the highway safety barrier designed to reduce the impact of hitting a concrete wall had previously been struck and was not repaired.

Tesla stood by their Autopilot feature in the blog post, saying that Autopilot still reduces automotive deaths.
"No one knows about the accidents that didn't happen, only the ones that did," the company said. "The consequences of the public not using Autopilot, because of an inaccurate belief that it is less safe, would be extremely severe."

Due to popular request of information on the last collision at the location, the California Highway Patrol's Redwood City-area office wrote on Twitter on Wednesday that the prior recorded crash was on March 12 around 10:30 p.m.
The NTSB spokesman said that the agency will work to determine the probable cause of the crash and provide an update in a preliminary report, which generally goes out within a few weeks of the completion of their field work.
"The uncoordinated release of investigative information can affect how other parties work with us in the future so we take each unauthorized release seriously," O'Neil said. "However, this release will not hinder our investigation."
