This is one of the many edge cases that I’ve been convinced will keep self driving cars from becoming mainstream unless/until true AGI is achieved.
A few years ago I stopped at a red light next to a construction site. I was watching the traffic light, so at first I didn't notice a cop at the construction site trying to wave me through the red light. He finally took a few steps towards me and yelled to get my attention. Only then did I realize he was waving me through, so I did just that. I seriously doubt any current self driving car would recognize a police officer (and not just a random pedestrian) that’s overriding the traffic signal like that.
Another edge case, coincidentally at the same intersection a few years earlier was when there was a car fully engulfed in flames as I drove up. I could hear sirens in the distance, and the cars in every direction were making sure to safely get out of the way of the approaching fire trucks. At least one or two cars cautiously crossed on the red to get out of the way. Again, I doubt any current self driving car would have navigated that situation anywhere nearly as well as a human.
Do I really trust humans to perform much better when traffic lights are out?
I can recognize when a police officer is directing traffic at a dead traffic light. I can also recognize the intent of other drivers who may wave, flash their headlights, etc. I doubt any current self driving cars can accurately recognize any of those.
If the power had just gone out and the mind was in thought – I could foresee you, me, or some Karen blowing through the intersection.
