1. The classification shouldn't happen from a single frame. In order to be misclassified as a shadow, the system would have to get the classification incorrect at various distances and you're probably moving too, so it would need to be across many frames.

2. This suggests that one sensor misclassifying will be sufficient for a deadly situation. But autonomous vehicles all use multiple sensors. They could even theoretically have multiple classification models running. One misclassification will not result in accidents.

3. Humans driving around effectively blindly is already an extremely dangerous situation.

4. This discussion is often limited to places where humans are distracted but overall trying to drive properly. In many parts of Asia (Korea, Taiwan, etc.) drivers very willingly disobey signals and are not at all deterred by the risk of hitting a pedestrian through their own impatience.

Humans are very dangerous behind the wheel. Hypothesizing about corner cases where autonomy might make a mistake is missing the forest for the trees.
