I wouldn't say the difference matters a lot. Instead humans and computers would just have different thresholds for when to stop and when to run over something.

I wouldn't say the difference matters a lot. Instead humans and computers would just have different thresholds for when to stop and when to run over something. If a computer is less accurate at distinguishing them, then it'll simply err on the side of caution more often than a human. You would find there are more inconvenient stops, not that more more babies get killed. I'm sure I've stopped for empty trash bags before because I wasn't sure if they contained something solid. That doesn't mean I failed as a driver. Everything went fine. Same if it's a computer but it might stop more often than a human.
