    @elonmusk tweets 19Jan2017:
    1: Final report on Autopilot issued by @NHTSAgov is very positive https://t.co/KsOZSrr3l9
    2: Report highlight: "The data show that the Tesla vehicles crash rate dropped by almost 40 percent after Autosteer installation."

    https://static.nhtsa.gov/odi/inv/2016/INCLA-PE16007-7876.PDF

    I was not aware of the underlined names.

    "These updates have included changes to improve TACC, AEB and Autosteer performance, as well as adding new driver assistance safety features, such as In-Path Stationary Object (IPSO) braking and Pedal Misapplication Mitigation (PMM). In September 2016, Tesla released its 8.0 firmware update which included revisions in the driver monitoring strategy, as well as several enhancements to AEB, DBS, and TACC performance."

    "As part of Tesla’s 8.0 over-the-air (OTA) software update in September 2016, Tesla revised the timing of the hands-on warnings and added a feature that takes away the Autopilot driving feature for the remainder of the drive cycle if the driver fails to respond to the alerts adequately (known as an “Autopilot strikeout” – Figure 6)."

    There's a lot of other fascinating data too. I'm still reading through the report, and will update with more things I find (emphasis mine):

    Finally, to paraphrase, the NHTSA's conclusion is that the crash is due to a period of at least 7 seconds of driver distraction, and Joshua's last input was a TACC speed change 2 minutes prior to the crash. If there's anything to take away from this report, it's the (intuitive) lesson that traffic conditions can change from uneventful to deadly in a matter of seconds. Had he looked up 8 seconds before the crash, he would likely have seen nothing threatening.

    So…. keep that in mind when evaluating the temptation of looking away from the road while using AP. I know I've been guilty before of looking away for a couple seconds while using AP.


    EDIT: Also, while 8.0 added In Path Stationary Object collision avoidance, there is no mention of Lateral Turn Across Path avoidance

    Reading more into the footnotes, I found these lines interesting too:

    It does seem like the NHTSA is trying to warn (automakers in general) that you cannot just hide behind blanketing warning statements in the manual, and egregious deficiencies in level 2 ADAS implementations can still be classified as safety defects.

    Of course, it did not find any such deficiencies in Autopilot.

    Let me guess: No.

    But that's not what the NHTSA data is trying to show. Simply put, comparing when AP1 HW was a decorative camera and radar antenna, versus a later date when FCW and AEB alongside TACC/AP were activated, serious collisions went down 40%.

    That sounds believable to me, and has more to do with FCW/AEB than Autosteer.

    The ability to see two cars ahead is a big deal for mitigating damage, accidents, serious injuries, IMO. What other companies cars implement this capability? I used AP (AP1) on my X even around the suburb 40-45 MPH roads (with both hands on wheel) and loved when it was watching two cars ahead. Lot of distracted drivers.
