You're right. Developing video games has taught me that a second is a long time. But we still don't even know that Uber didn't detect them that early. The CV system or other sensors could have picked out the pedestrian but something else went wrong instead.

I tend to think that if Uber did detect the pedestrian, they would have said something by now. But perhaps they prefer the optics of not having seen her to the optics of seeing her but not braking at all. We simply don't know.

Imagine that press conference.

> Uber: "After examining the black box on the car we have determined that the car detected the pedestrian but failed to brake."

> Reporter: "Was this because the pedestrian was a woman?"

> Reporter: "Did the car do this to protect the life of the Uber employee inside?"

> Reporter: "Was her credit score too low?"
