Can Lidar distinquish between an empty plastic white bag dancing on the wind in the middle of the highway, and a baby that fell out of a stroller? In both scenarios whether it can or cannot, its a distaster.

Many humans also won't be able to distinguish between inanimate objects and babies/animals on the road. When there isn't sufficient data, there isn't sufficient data. Machine learning is not magic.

yes, it definitely can. deep learning is what is used in these things, and identifies objects and their properties

      My apologies. I mistook your comment for "just sprinkle it with the magic dust."

I don't know why this is getting downvoted. That's on of the harder problems in vehicle autonomy.

  I wouldn't worry much. I have a few "fans" that follow my comments regularly and mass down-vote me. I also realized lately that my own upvote/downvote does not get accounted for.

Better than a human driver can detect a cat in the road. In fact a failure where it slows until it confirms with another sensor (probably optical) is ok. Many a driver won't even see the object and will drive though it.

That problem is hard, but because of cultural norms not as hard as it seems at first sight. You rarely will find that baby without a stroller next to it, and without a human close by hurrying towards it. So, if you avoid hitting that stroller and that human, and, next, avoid almost hitting that human, you probably are safe. A jury wouldn't easily convict you for accidentally hitting a baby that fell out of a stroller on the middle of the road and then was left alone without any adult supervision. I would think the difference between a solid object such and a piece of concrete or steel girder and various low-density objects (plastic bags, empty carton boxes) is harder. On the other hand, I guess it might be easier than laymen would think to use machine learning to build a "what's the density of the object on this photo" program that is in par with humans.
