Is the video slowed down? Also they need to release a better quality. If I was behind that wheel, I don't think I would've seen that lady to be quite honest. The place where the lady was crossing the road was under a shadow of nearby trees or buildings. If one is going to cross a road like this, they should at least use a well lit part of the road. Also, why did she have her back turned to the traffic if she is jaywa…

1) I wouldn't be surprised if that is the "best quality" they have. 2) I also suspect that human eyeballs would have a different view of the light/dark portions of what's depicted there, and especially eyeballs would have probably had a much higher chance of detecting movement in peripheral vision than that video gives any hint of.

I expect the original was probably much better quality. Twitter's video compression is terrible.

Direct link: https://twitter.com/TempePolice/status/976585098542833664 The interior view tells you everything you need to know about why anything except perfection in self driving cars will lead to more accidents. The driver specially selected and trained for exactly this job, does not look at the road! If someone specially trained for that won't do it, the general public certainly will not. Also, in the video you ca…

"The driver specially selected and trained for exactly this job, does not look at the road!" Humans gonna human. Our brains are trained by millions of years to not pay attention to things not directly important. It's hard enough sometimes to keep our attention on the road when we're doing the driving and the driving is too easy, like being alone on a highway at night. Expecting humans to passively observe driving whi…

Yeah, there's that videogame about driving a bus constantly, on an empty road, for hours and hours. It occasionally veers off, so you have to pay attention, but that's all. That game should be a minimum "driving" test for safety drivers. (Not really, but something like that)

I would hope self driving cars have better sensors. There are high dynamic range cameras that simultaneously take multiple exposures and composite them in real time. The dynamic range in this video is horrible. An HDR camera should have made her visible much sooner. Further why not use larger CMOS sensors, something like on a DSLR camera. Finally, the headlights appear fairly ineffective too. I would hope these cars are using Xenon headlights or something that does a much better job illuminating the road.

Earlier quoted context omitted.

That’s only because there’s no light on her until the end. The car hardware should have seen her. If it doesn’t work in the dark it shouldn’t be on the road imho.

Well, if we're demanding robocars that are better than people at this task, then that is a higher standard than we currently enjoy.

Literally everyone is constantly saying self driving cars will be better than humans. So, yeah, that's the standard.

Why is the resolution so low? Why is the FPS so low? Why don't we see the IR/LIDAR footage? Was the brightness adjusted after the fact to look favourably? Why didn't the vehicle issue a full stop once the woman was clearly visible? I feel PR handled.

The case has just come under NTSB investigation. This is not at all the sum total of information that will be revealed. https://twitter.com/NTSB_Newsroom/status/976215176323194880

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…

Indeed! To LIDAR, she was basically standing in the lane, with a bulky bicycle. To visible light, including the driver, who was apparently half asleep or watching the dashboard, she was in shadow until just before the collision. So yes, LIDAR should have caught this. Easily. So something was clearly misconfigured. And even if the driver had been carefully watching the road, he probably wouldn't have seen her in time.…

"And even if the driver had been carefully watching the road, he probably wouldn't have seen her in time."

I don't know about that.

1. Count the lane markers. (It looks like a astute driver could have stopped? Plus, most drivers might have picked up the reflection a bike gives off when head lights are flashed on it? Just a flash of light bounced off metal, or reflectors is enough to get my attention. There are times at night where I just notice a slight reflection in the peripheral of my vision, and I know to precede with caution, or slam on the brakes. It's usually an animal darting across the street. I don't think I've ever had to slam on the brakes for a bike.)

2. The woman looked at the car while it plowed onto her. She had a look of astonishment? Like why is this car running into me?

3. Uber is in deep trouble.

I think this brings up an interesting philosophy for autonomous driving technology - is it feasible if it's "only as good as human driving"? I mean I've seen comments that a human might not have seen the pedestrian. Is that a "defense" of driving AI? That's it's about as good as human driving? Seems to me the public won't accept driverless cars unless there is significant evidence that it's much better than human dri…

Undistracted, sober humans actually don't make a lot of mistakes.

Distracted and impaired humans do, and when a mistake is made we can put them in jail. Who can we put in jail for software errors?

It's very disingenuous to release this video. This is not the picture the car saw nor the human. That coupled with the fact that no radar or lidar data was released makes me wonder why the police seem to be bending over backwards to absolve Uber.
