How did LIDAR and IR not catch that? That seems like a pretty serious problem. It's clear from the video that a human driver actually would've had more trouble since the pedestrian showed up in the field of view right before the collision, yet that's in the visible spectrum. When I argue for automated driving (as a casual observer), I tell people about exactly this sort of stuff (a computer can look in 20 places at t…

Arizona and Tempe especially have lots of darker roads. The LIDAR/computer vision tuning at night doesn't seem right. Maybe it was adjusting for the changing street light brightness but yes this is one situation and the vehicle had just come from the Mill bridge that has festive lights that are strung along the bridge [1].

This is a situation though where the LIDAR should have clearly been better than it was. Maybe it was in a strange state after having seen all the lights and then complete darkness, looks like they were headed north on Mill Ave over the bridge [2] just past the 202 where it is indeed very dark at night and probably the spot right here [3] which matches up with the building in the background, the other way is South and is busy/urban by ASU. They had just crossed a lit up bridge, then dark underpass, then into this area [3]. The area that it happened in [3] does have bike lanes, sidewalks and a crossing sidewalk close by [4] but is by a turn out so not a legal crossing however there are lots of trails through there.

This video is worse than expected by far and may be forever harmful to the Uber brand in terms of software.

In AZ I usually see the self-driving cars out in the day, maybe there is lots of night tuning/work to do yet.

Timeline:

00:03 - The feet of the pedestrian are visible

00:04 - The entire body of the pedestrian is visible

00:05 - Collision occurs

If we assume that the computer only had this video as input, then the computer only had 2 seconds to avoid the collision. That would be unavoidable for the computer. But the fact that there was no sign of slowing down or braking in these 2 seconds is pretty alarming.

But it sounds unlikely that this video was the only input to the computer. Did the car have multiple cameras to "see" bright as well as dark objects at night? I would imagine that a self-driving car driving at night would use multiple cameras (tuned to various level of brightness) so that the car can match human level vision?

I wonder if this was affected by the fact that the pedestrian was in another lane up until the very last second. Perhaps the car detected the pedestrian but failed to consider it an obstacle since it wasn't in its direct path. It could be unexpectedly difficult to account for pedestrian crossing speed if it caused automated cars to stop when a car in the next lane happened to "wobble" towards the automated car's lane…

Even if you imagine it thought it was another vehicle stopped in the other lane of traffic, the SDV should have slowed. There's no way you should assume a stopped vehicle isn't hiding another danger and blowing through while speeding is what stupid humans do and what SDVs shouldn't.

In my high school drivers' education class, they specifically taught us to watch for feet that could be stepping into the roadway behind parked cars.

I do wonder if perhaps Uber made the video darker before releasing. Or used a camera that is not the main sensing camera. Because I would hope the cars are smart enough to increase ISO to get more detail at night time.

I wouldn't be one bit surprised. The antics of this company are well known. This incident has my wondering: of all the companies working on this, why is Uber trusted to be testing this technology?

trusted by _who_ in order to get approval for testing?

A number of comments here have touched on the fact that she was apparently homeless. I spent 5.7 years homeless. Well before that, I had a college class on homelessness and did an internship at a homeless shelter. I am author of the website the San Diego Homeless Survival Guide.

I've made a few comments in other discussions about some of the ways her status may have contributed to this tragedy. I'm just going to link to them with a short identifying blurb. Hopefully, taking them out of context won't make this go weird places.

Potential suicidal tendencies:

Potentially jaywalking dangerously and darted out of nowhere:

Possibly poor health contributed to her death:

I am leaving this here in part because "She was high or crazy" is a common stereotype about homelessness and it tends to not be a compassionate view. There are myriad ways her status could have contributed to the situation without her being either high or crazy. Yes, she could have also been one (or both) of those two things. But plenty of housed people get high or have mental health issues and we don't hand wave off their deaths as "they must have been high or crazy."

So, my hope is to be respectful of people whose feeling is her status could have contributed while putting out hopefully better information. Yes, her status may have contributed. But there is no reason to complete that line of thinking with "because homeless people are usually crazy and/or junkies."

There is a huge shortage of affordable housing in this country. A link backing that up is provided in one of my previous comments. These days, a lot of homeless people are just poor and can't afford rent, even while employed.

Anyone here have expertise on the current state of law governing autonomous vehicles? I know AZ is supposed to be lax compared to California, so I wonder if there is any situation in which Uber could be at fault (besides a civil suit from victim's family)? Let's say that the car's LIDAR was indeed dysfunctional, or obviously inferior compared to the industry standard. It could be a hardware problem, or the software a…

There’s nothing in the tort or criminal justice system that prevents responsible parties from being held responsible for negligently causing the death of a person in the realm of self-driving cars. If Arizona prosecutors don’t have enough for a case now, they might later after the NTSB investigation. No charges have been brought, so they could be brought up later. I would suspect that the backup driver would bear the…

What you wrote made me realize that regulations/laws about equipment/performance/computational standards would probably be managed at the federal level anyway (e.g. NHTSA). Though America is not necessarily the lead in autonomous travel, right? How far along are nations like Singapore and Germany in having legal frameworks for autonomous safety?

This seems like a simple case. I would have expected the driver assist in my 2017 Subaru to have reacted to something in the road. I'm surprised that the much more sophisticated self driving system did not.

I wonder if this was affected by the fact that the pedestrian was in another lane up until the very last second. Perhaps the car detected the pedestrian but failed to consider it an obstacle since it wasn't in its direct path. It could be unexpectedly difficult to account for pedestrian crossing speed if it caused automated cars to stop when a car in the next lane happened to "wobble" towards the automated car's lane…

I have a Forester as well, and it detects things in much wider angles. It even sees cars 160 degrees to the side of me and 30' away when backing up.

Why is the backup human driver staring at the dashboard most of the time? Should he not be closely watching the road? It appears he lost a few valuable seconds right before the collision because his attention was diverted to the interior of the car rather than focussing that attention on the streets?

It's clear from the video that a human driver actually would've had more trouble since the pedestrian showed up in the field of view right before the collision, yet that's in the visible spectrum. That's not at all clear to me. I don't know too much about cameras, but it looks to me like the camera is making the scene appear much darker than it actually is. In the video, you can see many street lights projecting down…

The whole reason many people on here have been advocating for self driving cars is that they can see obstructions more or less perfectly in the dark with LIDAR. I am much more interested in what that sensor said. I'm reluctant to infer exactly what a human eye would have seen in that situation. I have absolutely driven down streets in suburbia where the gap between street lights was large enough to make them quite da…

That is not the whole reason, it is one of many reasons.

> To be clear, I am not blaming the victim here, but do wear high visibility clothing when you're a pedestrian near high speed roads at night.

Yes, stupid homeless person.
