Apologies if this was covered in another thread .. If so my google-fu is weak
The NTSB report has been released and concludes that Tesla's autopilot was partly to blame for the crash.
My interpretation of the articles and reading some of the reports is that it gave a false confidence to drivers as well as not correctly detecting the truck.

It found that in 37 minutes of driving, Mr Brown had his hands on the wheel for just 25 seconds.
The documents also found that Mr Brown had set cruise control at 74mph (119km/h) which was above the 65mph speed limit.
In its report, the Safety Board said the truck should have been visible to Mr Brown for at least seven seconds before impact but that he took "no braking, steering or other actions to avoid the collision".
The report said that the car remained in autopilot mode for most of his trip and that it gave him a visual warning seven separate times that said "hands required not detected".
In six cases, the system then sounded a chime.
The US National Transportation Safety Board (NTSB) has found that Tesla's Autopilot system was partly to blame for a fatal accident in which a Model S collided with a lorry.
Federal investigators say Tesla "lacked understanding" of the semi-autonomous Autopilot's limitations.
"In this crash, Tesla's system worked as designed, but it was designed to perform limited tasks in a limited range of environments," Christopher Hart, a member of the NTSB said in a meeting to discuss the findings of its investigation.
"Tesla allowed the driver to use the system outside of the environment for which it was designed, and the system gave far more leeway to the driver to divert his attention to something other than driving."
Following the meeting, the NTSB's report includes seven safety recommendations requiring car manufacturers to add safeguards to prevent automated vehicle control systems from being used outside the conditions for which they were designed.
Tesla has yet to respond to the NTSB's findings.
