I also believe headlights were misaligned — Too low. Also believe due to no visible oncoming traffic, I would have hi-beam on. And that would have seen her in time to stop.
I think the low beams were about right. But I agree that high beams would have saved her life.
But these are all mistakes a human can make while driving. I had a real epiphany when it was pointed out to me that self driving cars don’t have to be perfect. They just have to be as safe as human drivers. And that’s not really that hard. :)
