      but they apparently aren't detecting the "obstacle" far enough in advance to brake safely.

      To my understanding, this isn't what Tesla drivers would call TACC ("Traffic Aware Cruise Control", aka smart braking based on the vehicles in front of you whilst in cruise control), but rather implementations of AEB (Advanced Emergency Braking) that is becoming legally mandated in many European countries soon. Basically, much more primitive forms of computer awareness designed as a backstop for truly emergency situations where the only goal is to save the occupants inside, no matter if there's damage to the car. So I wouldn't expect the cars confronting this scenario to brake safely—in fact, by design they only brake unsafely.

      That being said it would be interesting to see how TACC-like software—or Tesla's autopilot—handles this. It seems to me this is the first example of what I can only describe as the "iPhone effect" for vehicle autonomy (I'm sure there's a better term), whereby instead of our phones conforming to the world around us, like fitting in our pockets; the phones dictate the design of the rest of the world: jean pockets got bigger, especially for women, after the introduction of smartphones.

      I'm feeling increasingly confident Level 4 SAE is going to be solved not just by advances in computer vision and machine learning, but by also making the transportation world around us "simpler" (think: modified signs, elimination of problem-causing road designs, reductions in blind spots, etc).

        Now, the very limited beta of FSD (Full Self Driving) would be interesting, but I don't know if it would navigate this well either, given how narrow it is. I wouldn't put it out of the realm of the possibility though.

          Don't Tesla's still have that issue where if they detect a static object, they actually just continue driving towards it until they careen into it? That's been a cause of a number of high profile deaths, including Walter Huang, an Apple engineer.

            Have their been any deaths recently? The ones I am aware of were a few years ago, and the algorithms see constant updates. I believe the issue with the radar ignoring objects was on highways, and these barriers occur on smaller roads.

    Where I'm from cattle grids are always in driveways, not on the roads themselves. Can anyone shed light on why in the world you'd put one on the road proper?

        That makes sense, I'm from the Midwest US where we don't have open moorlands. Around here everything is private property and is fenced along the road.

          Cattle guards like this are quite common in the Western US as well. They're most often encountered on the borders of Federal land that is sometimes leased for grazing but also open to the public.

        Obviously they do not mention the specific make, but if its Tesla that would not be the case. Cattle Guards in roadways are standard everywhere in the US with open pasture.
