When I think of self-driving car technology, I think of all of these inputs (maps, cameras, GPS, etc.) being fed into a world model from which inferences are drawn.[1] Here, the car could have known from cameras and maps that there was a lane split, and should have been able to detect that the line following was giving a conflicting inference compared to those other sources. The question is: does Tesla actually do th…

The whole problem seems to me that to get a 90% solution for a self driving vehicle is now no longer hard. The remaining 10% is super hard and the degree to which the present day solutions tend to get these wrong is worrisome enough that if the quality doesn't jump up very quickly the whole self driving car thing could end up in an AI winter all of its own making. And that would be a real loss. This is not a field wh…

This is where my chief complaint with Musk comes in. His whole bravado as a salesman is probably having a longer term impact on AI for cars. He keeps pushing this auto pilot when it's not.

I agree with all you've said. One of my concerns with self-driving systems is that they don't have a good model of the world they are operating in. Yes, sure, they build up 3-D models using multiple sensor types, and react to that accordingly, oftentimes with faster reflexes than a human. However, consider this situation with pedestrians A and B, while driving down a street, approaching an intersection. Pedestrian A,…

Another similar situation where autopilot may fail. It sees a ball rolling across the street. Will it slow down, because a child maybe chasing the ball.

I think more people need to embrace and understand the fact that we are a long way from having fully autonomous vehicles that you can just give the steering reins to from start to finish. The term 'Autopilot' gives off the wrong idea that the driver can sit back and relax while the car brings you from point A to point B safely. The same is happening with chatbots - more and more businesses think they can put a chatbo…

Agreed, the "but that's not how autopilots w…

Yep it took Google/Waymo 8 years to get there but Musk and Uber just wants to move fast and crash into things. Musk wouldn't be selling self-driving since Oct'16 if it's not any day now or would he ?

Here is my armchair diagnosis: right before the car veers towards the barrier it drives through a stretch of road where the only visible lane marker is on the left. Then the right lane marker comes into view at about the point where the lane starts to widen out for the lane split. The lines that will become the right and left lane markers of the split left and right lanes respectively are right next to the van in fro…

In other words an old ambiguous parsing problem.

It might be fixable in software. I'm a bit annoyed at Tesla for over reliance over painted lines. They fade, they can be covered, be outdated ..

That old fail video of a SDV stuck inside a circle is not funny anymore.

So human drivers are terrible at driving for any long period of time, especially on relatively consistent "boring" highways. Guess what computers excel at? Driving consistently on consistent highways. The Tesla Autopilot is supposed to be the always aware and paying attention portion on these cases where a human driver would be very likely to start texting or dozing off. Now, it's not fully autonomous and may well de…

Guess what computers excel at? Driving consistently on consistent highways. Watching the video, would you say the computer was excelling, or that the road was radically unusual? I wouldn't.

The location is the end of some tidal flow lanes rejoining the main freeway lanes with an unusual configuration of lane markings and barriers. I drive past the spot all the time and can totally see a computer messing up here.

Elsewhere from the comments: "Yes the lane width detection and centering was introduced in 10.4. Our X does this now as well and while it's a welcome intoroduction in most cases every one in a while in this instance or when HOV lanes split it is unwelcome." So basically, if I'm understanding this right they introduced a new feature that positions your car a little more consistently in the lane at the small cost of so…

And that's exactly what makes Tesla PR so disingenuous, they know better than anybody what updates they did and how often their updated software passed that point and yet they will happily cite numbers they know to be wrong. So, now regarding that previous crash: did that driver (or should I say occupant) get lulled into a false sense of security because he'd been through there many times in the past and it worked un…

I'm a huge fan of Tesla and I thought that bit of PR was horrifyingly bad. It came across as completely dismissive of any further investigation or accepting of even the possibility of responsibility.

Now that these other videos are showing up, and further details (the update) are emerging, that PR should bite them in the ass hard enough that they decide never to handle an incident that way again.

I don't want this to kill Tesla -- I sincerely hope they make their production goals and become a major automobile manufacturer -- but their handling of this should hurt them.

I'm also curious if any of the people at Tesla saying, "we call it autopilot even though we expect the human driver to be 100% attentive at all times" have studied any of the history of dead man's vigilance devices.

Estimating errors or confidence level reliably is still one of the biggest unsolved problems in AI.
