    even i have difficulty with covered old road lines and new ones going a different direction, especially in construction area's. those are slow down and process correctly situations.

    Indeed. In this discussion, we have to remember that suboptimal road conditions can confuse human drivers too, and human-driving mistakes (there are many) don’t make the news.

    On the upside though, there are many mistakes that humans are likely to make that Autopilot (and similar) is very unlikely to make, such a failing to see cars in the target lane of a lane change. Conversely, there are mistakes, like those we’re discussing here, that humans are less likely to be fooled by. Therefore, we can get the best of both human and computer strengths!

    we can if as you said, 'we stay alert while the car is doing its thing.' but that is a concern as well. we could wind up with human mistakes, and computer mistakes not corrected by inattentive humans.

    Tesla now blames the driver in last month's crash for not paying attention to Autopilot warnings.

    "We are very sorry for the family's loss," a Tesla spokesperson told Business Insider in a statement.

    "According to the family, Mr. Huang was well aware that Autopilot was not perfect and, specifically, he told them it was not reliable in that exact location, yet he nonetheless engaged Autopilot at that location. The crash happened on a clear day with several hundred feet of visibility ahead, which means that the only way for this accident to have occurred is if Mr. Huang was not paying attention to the road, despite the car providing multiple warnings to do so.

    "The fundamental premise of both moral and legal liability is a broken promise, and there was none here. Tesla is extremely clear that Autopilot requires the driver to be alert and have hands on the wheel. This reminder is made every single time Autopilot is engaged. If the system detects that hands are not on, it provides visual and auditory alerts. This happened several times on Mr. Huang's drive that day.

    "We empathize with Mr. Huang's family, who are understandably facing loss and grief, but the false impression that Autopilot is unsafe will cause harm to others on the road. NHTSA found that even the early version of Tesla Autopilot resulted in 40% fewer crashes and it has improved substantially since then. The reason that other families are not on TV is because their loved ones are still alive."

    That isn't what they said, but when you get right down to it, that is where the blame lies.
    Now, it may have been a medical issue, or something else which most would find 'excusable'. However, it comes down to the driver made no effort to avoid the crash. Was likely not aware of it, as his attention was, apparently, elsewhere.

    Nikki Gordon-Bloomfield here:



    Pointed out an important detail in this case: The crash attenuator has been crushed already by a prescient accident and not yet repaired.

    My comment on that video:

    You mentioned in passing an important consideration: the collision attenuator at that location had been crushed due to a previous collision. In other words, as tragic as this event was, the sad reality is that these sorts of tragedies happen all the time, Autopilot or not. All in all, they happen less often with Autopilot, ProPilot, Super-Cruise (etc.), but sadly, it’ll be a while before they become a thing of the past. That fact also tells us that this site has managed to confuse human drivers too, and possibly pretty often so, since it hadn’t yet been repaired from the previous collision. So it’s not entirely a ADAS-unsophistication issue; it’s “just” a sad tragedy on the road.

    @235...which is where the problem lies. People don't want to pay attention. They want an automated Chauffeur so they can poke glass or what ever. "AutoPilot" and Autonomous Cars are not the same.

    To be proactive, Tesla and others should give their systems the ability to determine if the driver was incapacitated, like from a stroke or seizure, and takes steps to pull over and call for help.

    There are a lot of videos out there showing how to trick the Autopilot by shoving a large piece of citrus fruit in the right side of the steering wheel.

    I'm not saying or implying that is what happened during this particular crash, only that this appears to be a very popular way to fool Tesla's hardware and software.

    Maybe they need to periodically check for "warm body that is an awake, aware human with functional cognitive senses". Rule out fruit, pets, stuffed animals, fake fingers, sleepy/ill drivers, and so forth.

    Careful on the popularity assumptions. I know of no one that actually uses that trick. Sure, it has been posted to youtube. Similar videos are out there fore Mercedes and many other cars. It doesn't mean many people do it.

    Having a system that is not so easily fooled is a good idea, but how much are you willing to pay for it?

    The recovered data shows that there were autopilot warnings to the driver.

    She does make some good points.

    Another member posted a video of a Tesla driver showing how his car showed similar behavior approaching an off ramp on the Dan Ryan Expressway in Chicago.

    There were some disparities in that situation: the white line for the off ramp was clear, the marking for through lanes were not; the crash attenuator barrier was intact, and rumble strips (audio cues) were present.

    There may be different lane marking standards in use at the time each highway was built. In Chicago, rumble strips are frequently used on expressway and tollway shoulders. If nothing else, the noise will wake you up.

    I don't recall seeing or hearing rumble strips during my limited driving experiences in California, and I haven't encountered them any place else I've lived. Maybe that's a Northwestern Traffic Institute thing.

    Personally, I thought her best remark was to get all the car companies and international bodies on the same page about the subject. That might be a good idea before we put the cart much further in front of the horse.

    If Pilots set up autopilot-autothrottle-autoland, even with ADIRUs, TCAS, LRRA, ATC, VHF Comm, ect...(everything with redundant systems) and they crash...guess who's fault it is if they do/did not visually monitor, listen and react to the surroundings, instrumentation, broadcasts and warning systems, ect...

    Ground vehicles in congested, non-controlled, un-maintained environments with a single closed system...come on people.

    Ground vehicles in congested environments, with maintained vehicles on "autopilot" would be Disneyland, and you'd need to wait in line all day and hand over your E ticket to get a ride.

    The point I'm making is peoples expectation and confusion with A/P vs autonomous vehicles is skewed.

    I know they have stated plans for it, when the driver is unresponsive, to pull the car over to the side of the road, stop and call 911. I don’t know, however, whether that has in fact been implemented yet, though.

    I personally think the best would be eye tracking, which I think I recall Daimler is working on. What matters most is not that you tug at the wheel every now and then, but that you’re paying attention to the road situation.

    I'm not sure a single check would be sufficient. Some idiot would find a way around it, although it would be technologically more difficult than a citrus fruit.

    Use the eye tracking and something else. Perhaps something random the car asks you to do on a timed basis, but not something as simple as put your hands on the steering wheel every few minutes.

    Tesla says "touch the turn signal". Tesla says "touch the emblem on the steering wheel". Put your hands on the wheel. Sorry, you lost that time, Tesla didn't tell you to do that!
