Tesla: Model X Accident Caused By Driver Error, Not Autopilot (computerworld.com)

An anonymous reader writes: Tesla has responded to a recent report from a Model X owner claiming their vehicle suddenly accelerated at "maximum speed" by itself, jumped a curb and slammed into the side of a building while his wife was sitting behind the wheel. They said it analyzed vehicle logs, "which confirm that this Model X was operating correctly under manual control and was never in Autopilot or cruise control at the time of the incident or in the minutes before. Data shows that the vehicle was traveling at 6 mph when the accelerator pedal was abruptly increased to 100%. Consistent with the driver's action, the vehicle applied torque and accelerated as instructed. Safety is the top priority at Tesla and we engineer and build our cars with this foremost in mind. We are pleased that the driver is ok and ask our customers to exercise safe behavior when using our vehicles." When will people stop lying about Tesla's Autopilot mode crashing their cars? One Tesla owner recently filed a Lemon Law claim against the company over a high number of quality control issues.

    Not being funny...

    but if the logs show 100% acceleration, that just reflects the sensor value. Not that the user - or indeed anything else like a dropped handbag - actually pressed the pedal that far.

    Although I'm always the one to shout "user error" first, and that's quite likely in this case, the logs alone are not sufficient to prove fault. Only to act like a flight recorder and say what the sensors recorded and what the machine did in response to that input.

    How the sensor got that reading could still be manufacturing fault, cable fatigue, or a million and one other things not the fault of the driver.

      I think the bigger point is that the car wasn't in autopilot mode at the time. I don't think the drivers are realizing that they can check and call them on their bullshit.

      If you're building a safety critical system, having two sensors won't do you much good. Even if they disagree, you have no way to know which is wrong, only that some fault exists. The best you can do in that situation is try to fail to safe, but in a vehicle where stopping suddenly at the wrong time or in the wrong place could be more dangerous than carrying on until it's safer, there is no perfect failsafe mode.

      Having three parallel systems, ideally made with different types components to guard against design defects, gets you something more useful, since you can at least take a majority vote if one of the sensors is out of sync with the other two. Obviously this is also more expensive to implement, though.

      There's nothing preventing "45 year old wives" from knowing something about the machines they operate. Actually, I do expect people operating machinery that can lead to accidents that endanger the lives of others to know enough about them to operate them safely. Independent of gender, race, age... you get the idea.

      Users are also capable of not telling the truth. The logs are almost certainly accurate.

      That doesn't entirely rule out a fault - if the system erroneously reads a 100% accelerator pedal depression, then it will record that and act on it; the error then being in the sensor, not the logging or action taken by the car.

      But when somebody is parking, they are going to press the brake to stop - and if they find they are not stopping, or accelerating, they'll press it harder. So a 100% depression is also consistent with someone mistakenly pressing the accelerator instead of the brake.

      When you make it possible to the blame the car, some people are going to do so instead of taking responsibility. On balance, I'm inclined to believe this was user error.

      Technology is about to be mandated that will stop incidents like this; mandatory Automated Emergency Braking is coming in what, 2020? 2025? Real soon now, since all the major manufacturers and suppliers have an AEB solution available. And then "wrong pedal" collisions will be a thing of the past. The car simply won't let you do that.

      It's too bad enough of us couldn't be responsible for humans to be able to keep the responsibility of driving, but more and more of it is being taken away.

    I did this a few weeks ago.... I was driving along a fairly empty road and had to go past a parked vehicle, so I tapped the brake and to my horror the car went faster! I realised afterwards that I'd been driving for a while and I wasn't sitting completely straight to the wheel, so my feet weren't aligned with the pedals. Then I moved my foot across, too far, and now I was punching between the clutch and the brake (pressing both pedals, but weirdly because they have different pressures) - nothing was working, total madness! It was dark and i couldn't see my feet, and I sailed past the parked car at speed before I finally realigned and got back in control.

    Whereupon I straightened myself up, slowed down, and spent the rest of the journey muttering shit...shit...! It'd never happened before, I didn't even consider it a risk. Scary.

  3. Are the logs readable by anyone but Tesla? by FlyHelicopters · · Score: 4, Insightful

    Serious question... is this open information that the driver or owner of the car can read, or is this super secret encoded info that only Tesla has access to?

    Do we simply take their word for what the logs say? Is there any way to check via 3rd party that this is in fact what happened and there is a secure means of ensuring the data isn't changed?

    This is important, sooner or later it'll end up in court and this will come up. "Trust us" is not an answer.

    That was my question exactly.

    Why does no one object when I place a camera on the floor of a factory for safety reasons?

    But everybody gets hysterical when I place that same camera in the employee toilet looking directly at the employees taking a dump?

    What's up with that?

    His suggestion was that *everyone* puts fashion before safety, and that the difference is primarily because social norms prevent males from wearing similar footwear. That you somehow interpreted it as "women are the only ones who put fashion before safety" is intriguing and rather telling.

    This is a key piece. I was astonished when I bought a new car how different everything felt for a few weeks. I'd had the old car for 12 years and everything was second nature in it but it takes a while to get used to a new vehicle's layout and handling.
