Public release of Tesla Autopilot accident report

Insurance Information Institute (I.I.I.) chief actuary James Lynch and I.I.I. research associate Brent Carris share insight on the Tesla Autopilot accident report:

The National Transportation Safety Board (NTSB) released 500 pages of documents on last year’s fatal Tesla Autopilot accident in Florida. Per the initial press release the report contains only factual information on the investigation including highway design, vehicle performance, human performance, and motor carrier factors.

In an email newsletter he writes, autonomous vehicle expert Alain Kornhauser (Princeton University) raised some questions and concerns regarding the report. Those include:

  1. Since lateral control (swerving) couldn’t have avoided this crash (the truck is almost 70 ft long (6 lanes wide) stretching broadside across the highway) , it doesn’t matter if Josh Brown ever had his hands on the steering wheel. That’s totally irrelevant.
  2. Why didn’t autobrake kick in when the tractor part of the tractor-trailer passed in front of the Tesla?
  3. How fast was the truck going when it cut off the Tesla? I couldn’t find the answer in 500 pages.

The full 500 page report is also available to view at NTSB: Docket Management System.
