Newest Tesla Autopilot Data Shows A 40% Drop in Crashes (bloomberg.com) 167

Posted by EditorDavid from the Autopilot-is-my-copilot dept.
There's a surprise in the data from an investigation into Tesla safety by the U.S. National Highway Traffic Safety Administration. An anonymous reader quotes Bloomberg: [W]hile all Tesla vehicles come with the hardware necessary for Autopilot, you need a software upgrade that costs thousands of dollars to make it work. Since buyers can add Autopilot features after purchase, this provides a perfect before-and-after comparison. It turns out that, according to the data Tesla gave investigators, installing Autopilot prevents crashes -- by an astonishing 40 percent...

Now -- thanks to an investigation that initially hurt the company -- there is finally some real data, and it's good news for Tesla... As the software matures to match the new hardware, Musk said on Thursday via a Tweet, Tesla is targeting a 90 percent reduction in car crashes.
UPDATE (5/4/18): The NHTSA has now clarified that their study "did not assess the effectiveness of this technology.

UPDATE (2/16/19): The study's underlying data reveals serious flaws in the methodology that undermine its credibility, according to new analysis from a research and consulting firm.

    I think the technology is a good idea, but they've picked a terrible name for it. To someone who is uninformed, it makes it sound as though the feature enables automated driving for the vehicle, and while that may be the end goal, it's currently not at that level and may give a false sense of capability. They should refer to it as "Driver Assist" or something that doesn't leave anyone with a false impression of the capabilities of what it does.

    • Absolutely. And they should make it much more clear that drivers should keep their hands on the wheel at all times, which autopilot doesn't imply.

      • There is some mild rebuking if you don't hold the steering wheel.

        If you don't hold the steering wheel then after a time between 1 and 5 minutes (depending on situation) you get an audible and visual warning. Ignore the warning for 15 seconds and you get a "strike". 3 strikes within an hour and you're out: you won't be able to use autopilot until your next journey.

    • Agreed. If I bought a car with a feature called "autopilot", I would think I would be comfortable taking a snooze (or watching a Harry Potter movie) while the car did the driving for me. I am really surprised they haven't dropped the name "autopilot" as it is totally misleading and something that has been pointed out repeatedly.

        I agree completely. I'm actually surprised that they haven't been sued for false advertising instead just like the cell phone companies have for "unlimited". It should be called "Driver Assist" until the driver is allowed to nap. Yes, I know that a pilot isn't allowed to nap but that's not really the point. A pilot has had a lot more training AND is less likely to hit something if it does dose off AND usually has a second pilot as well.

        Yes, it absolutely could have. Driver's are now more aware of the limits of autopilot and are using it more responsibly. The sample set 'before' installation includes all driving before the rash of media attention. We may have seen a similar drop in the rate with no installation.

    Expect media outlets whose owners will benefit financially from Tesla's failure to report this in a negative light, bury it, or begin advertising sponsored competitor's autopilot as being superior.

    Does anyone have a working link to the actual report? It was supposed to be at static.nhtsa.gov/odi/inv/2016/INCLA-PE16007-7876.PDF
  • when I got creamed out on my road bike, assuming it can detect pedestrians. I was carrying the damn thing across a cross walk (with the little green walky man no less) and somebody ran the light. They clipped the wheel of my bike or I wouldn't be here right now. The lady stopped. It as broad daylight but somehow she didn't "see" me. Folks tune out when driving. That light almost never turns red so it didn't occur to her to stop. Put another way they're driving with their lizard brains. I'd rather they do it

    • My new car is supposed to see pedestrians and brake to stop them. I haven't actually tested this yet, due to a lack of experimental subjects.

  • installing Autopilot prevents crashes -- by an astonishing 40 percent...

    I think everybody knew that a solid autopilot system was going to be better than human drivers on average. Why is the author astonished by this?
