>Well, for one people do not expect drivers to stop at a green light, like was the case here. You might wish everybody was well aware of their environment, but the fact is, a green light is a strong signal that makes people assume the other drivers are moving or are going to.
Watch the video. The self-driving car braked because the two cars in front of it did.
Hmm... of course it did. It's not a human. The green light vs. stopped traffic can't mislead it the same way a human can be misled through inattention.
The car behind the self-driving car didn't stop though, which lead to the incident. Presumably because it didn't pay attention to the fact that the cars in front were not moving despite the green light.
I'm not sure I understand where this thread is leading.
