How does Tesla FSD respond to inactive traffic control lights?

Coincidentally we were on the Robotaxi during the black out (didn’t know about it, we were going to Japan town from the Mission). Noticed that it navigated through the non-working traffic lights fine, treated it like a stop sign junction. One advantage of building unsupervised system from public version that had to deal with these edge cases all around the country.

Though the safety driver disengaged twice to let emergency vehicles pass safely.

Treats it as a four way stop.

Looks like it treats it as a 4-way stop. Is this because Tesla has more training data?

50/50 bet it would either go right through or treat it as a stop.

Don’t think I have had a totally inactive light. I have had the power is out but emergency battery turned to blinking red light, and it correctly treats as a stop sign.

Its human takes over. FSD is still Level 3.

(Robotaxi, Tesla's Level 4 product, is still in beta. Based on reports, its humans had to intervene.)
