I'd like to see how the dummy looks like from the perspective of the car. If they painted the back side with a pattern of the road, then of course a car without Lidar can't see it. But neither could a human driver. "Thing on street" detection is probably the most basic function of an autopilot, after lane keeping. I would be surprized if there wasn't a robust "thing on street" detector as a separate module in front of, and separate from the whole self-driving AI. As far as I heard, simple obstacle detection can already be made more robust than human vision, just with stereo cameras. Now what is hard is, stuff moving perpendicular to the road. Child running towards the road behind a chain-link fence is OK, but if there is no fence, stop immediately. Is that rolling thing a tumbleweed, or a ball? And so on...
