Ok, Mobileye would have seen the pedestrian 1 second before impact. That's not important though... The important thing is would it have saved her life? Would it have taken action and if so when and how? It's not clear that Uber's platform didn't see the pedestrian. In fact, I find it unlikely that it didn't see her, between radar and the bike, lidar, and optical (and sonar). I think the situation here is that there were many failures and decisions that led to this death. Some of it is Uber being too cowboy, but there are a lot of other factors too.

> The important thing is would it have saved her life? It probably would have. Slamming on the brake for 1 second would have reduced the car's speed enough to change things from fatal to seriously injured. According to: http://www.batesville.k12.in.us/Physics/PhyNet/Mechanics/Kinematics/BrakingDistData.html http://www.batesville.k12.in.us/Physics/PhyNet/Mechanics/Kin... In one second you can shed 20 miles/hour of speed. That would take the car from 38mph to 18mph. (Those numbers are overly precise, but gives you an idea of the reduction that can be accomplished.)

  The car could have also swerved and missed her entirely. IF it decided to take action. That is the point I'm trying to make. Saying your product would have seen the pedestrian is very different from saying it would have seen her and known to immediately take action and the action it would have taken would have changed the outcome.

  Not only that, she was crossing from left to right and was hit by the edge of the right side of the car. She could have been missed entirely.

At 45mph the car is traveling at 66 feet per second, so 1 second before impact means it was spotted at approx. distance of 66 feet. The volvo XC90 breaking distance at 62mph is 112 feet. Dividing by the square of the speeds gives us a 45mph stopping distance ~62 feet. So not only would it have saved her life, it could possibly have prevented the car even touching her. (The XC90 has excellent breaking, btw, better than a range rover sport or an audi Q9).
