Emergency braking is part of autonomous driving, so ...? Anyways, my VW has assisted emergency braking. I've had opposite issues - water splashes across sensor and the car brakes for no good reason. Generally going through a large shallow puddle and moderate speed. Happened 2 or 3 times and now I disable when driving near the beach after rain.

  "Anyways, my VW has assisted emergency braking. I've had opposite issues - water splashes across sensor and the car brakes for no good reason.

Your "issue" is essentially the system being extra safe - similar to slowing down when a bunch of water hits your windshield. Seems highly appropriate to me.

    Except it's a full-on emergency brake reaction and liable to get me rear-ended. Per the initial discussion, there are places (and this is one) where a human is still MUCH better at assessing the situation and acting appropriately.

      "Per the initial discussion, there are places (and this is one) where a human is still MUCH better at assessing the situation and acting appropriately." You've done nothing to support that assertion. "MUCH better at assessing the situation and acting appropriately" doesn't compensate for 10x slower reaction time. Nor does it account for the high percentage of time that humans are paying attention to something besides driving. Machine systems don't get distracted, at least. We'll agree to disagree, but anticipate fully autonomous cars sooner rather than later. ;-)

  "Emergency braking is part of autonomous driving, so ...?" So, the Tesla issues involved not identifying objects in the field of regard correctly, and thus not steering appropriately. Brake systems weren't involved in either crash, IIRC. Assisted emergency braking is much more narrowly focused than full autonomous driving. It doesn't care what the object is, if it's solid, in front of the vehicle, and in it's path, the system will brake. These days it potentially has vision, sonar, lidar and radar to provide sensory input. That's a whole lot more information than a human can access.

    I have no idea if the appropriate reaction in these cases would have been braking, steering, or some combination. Regardless, current autonomous vehicle systems (whether they claim to be full auto-pilot or just emergency braking assist or lane-keeping) have some pretty massive blind-spots.
