Ah, no, the cars only need to be better than humans, not perfect. This seems self evident, so did you mean to communicate something else?

Better than humans on average or better than the best human?

If there is something that isn't going to help the public perception of autonomous cars at all, it's releasing a compressed to shit capture of another video showing a single camera angle from dozens. I would say it's a deliberate attempt to manipulate if I didn't also strongly believe ignorance on part of the police department has lead them to believe that autonomous cars could even exit a parking lot without data fr…

Yeah. Does the Uber car really capture video at 480p and 15fps? Also only releasing the video conveniently ignores the fact that these cars have IR and LIDAR. The pedestrian is hard to see in this video essentially because it is dark and they are wearing dark clothing. Neither of these are at all obstacles to LIDAR and IR, and the video at least shows us that the road is clear of obstructions.

>Does the Uber car really capture video at 480p and 15fps?

Probably not, but it isn't like the inputs to the self-driving models really need to be better than that. Lower resolution helps your processing time a lot and there's little point in having an FPS higher than your processing time.

As presented, this looks like a pretty classic "overdriving your headlights" situation. Even though they're made of retroreflective material, only two lane divider dashes at a time can be seen in the video, indicating something like 50 feet of visibility. Stopping from 38 mph takes 70+ feet from the time the brakes are applied (and human reaction time adds quite a bit more). Things (people, animals, stopped cars, roa…

The car didn't slow down even after it hit her, I think there was a different 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. This was taken by a video camera - which has a much lower range of detectable brightness then the human eye. The pitch-black spots in the video are almost certainly not pitch-black if you were to look at them.

This car should have slowed down below the speed limit if it cannot safely stop or maneuver upon seeing something enter its field of view.

This does not seem reasonable. Should it drive at < 35 MPH on highways at night? That's probably even more dangerous.

This is such a blatant attempt to manipulate public opinion before the actual data appears. Even if Uber's software is ridiculously using visible light for its decision-making, it should definitely be taking into account what it doesn't know. A system like this should not be guessing. There is a giant swath of black in the video; the camera doesn't know what's there. So, the car should be moving so it has a short eno…

Some of the comments in this thread are ridiculous, and your comment throws them into sharp relief. Even if the video is a perfectly faithful reproduction of the scene and the dark parts are that dark, why in the world would the software assume a space it has next to no information about is safe to drive into at the current speed?

> a space it has next to no information about

The car is equipped with more than just an RGB camera sensor wise, such as the Velodyne LiDAR, so it does have information about the scene despite being pitch black to the naked eye.

Whatever the outcome of this case, autonomous cars are not going away. That cat is already out of the bag. As for this accident, I think in time it will be shown in time that while machines can make mistakes, they make fewer mistakes than humans. Six years ago I heard that CSX (a major rail line in the U.S.) was actively pursuing autonomous trains. I thought the idea was horrible, until the programmer working on the…

I’m actually not. I’m agnostic about the technology, and I don’t care for Uber either for or against, and am not defending them nor am I interested in attacking them.

Just being realistic, looking at the big picture. Realistically speaking, this tech will be improved in time.

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…

I’ve driven that location on that road many many times at night and no it is not that dark, it is lit up well like most city streets. The video make the contrast appear greater.

If you could it would be very valuable if you did a test at that location and shared your experience
