Not clear why did the car continue to travel after the impact. Didn't the systems detect the negative acceleration from the collision?

  It wouldn't necessarily be cause to disengage the autopilot. Plenty of things could cause negative acceleration besides a collision. A hill, a patch of mud, etc. And presumably they didn't anticipate this kind of situation, so didn't include moderate slowing due to collision as a code path.

    The car should still have started emergency braking at some close distance before the obstacle (when the radar data got very clear about that not being an overhead sign). Braking in case of an inevitable crash is useful to reduce severity of the crash. And it's a bad idea to release brakes after the crash either. So it still seems like wrong behavior to me.

      Well of course it's wrong behaviour! But in the article itself it says the car never braked, as it did not see the trailer. Presumably it did detect some deceleration and compensated for it. I'm just saying that apparently it wasn't programmed to interpret sudden deceleration absent any other indicators as a possible collision. I agree that perhaps it should be.

  You can't stop momentum like that on a dime.
