Is there a technical explanation anywhere for why this is so hard for the system to handle? I get that if a car ahead of you suddenly swerves out of the way, revealing a stopped vehicle that was completely blocked from view previously, that the vehicle (like a human) can't react until it sees it. But it's clear the vehicle had time to react and didn't until the crash was imminent.

Think barriers around a curve. The car doesn't know that you're going to turn so it must ignore stationary objects(for now). To the sensor suite following an S-curve might look the same(car following going right). That said it seems like AP/AEB aren't cross-sharing data and could do better there.

[edit] Looks like AEB did engage at the last minute, but that only happens when there will be a collision.

So at this point that the lane-keeping (automatic steering) wasn't engaged? How did the guy let this happen if he was steering at the time?

I'm not completely sure but I believe it has to do with the decision to not use LIDAR, in favor of just a camera and some other basic "radar" system. The cost of LIDAR is pretty expensive, yet coming down. I imagine in their AP 2.0 hardware update, it will include LIDAR for all directions. Like Google's car.

Some companies are working on solid state lidar in the price range of $250.

My Subaru (which just uses cameras) definitely would've stopped for this. Perhaps the difference is that the Subaru uses two cameras to get a stereo view, whereas the Tesla is trying to do it from a single camera.
