Rhetoric spewing forthcoming... I talk about this stuff with my peers, and am constantly dismissed by the techno-optimists that believe in the promises of big tech, but I think it is important not to jump the gun and put these self-driving cars into production (i.e. the real world) without a significant paper trail and analysis of real-time incidents being made available to the public. Full stop, all incidents and outcomes, not just the good.

Going further, I wish for more initiative to re-design infrastructure putting the safety of pedestrians, cyclists etc at the forefront. It is simply not safe for alternative transportation to share the road with vehicles, autonomous or otherwise. Coincidentally, if infrastructure were designed to limit or prevent the interaction between cars and non-cars, the problem of detection for autonomous systems becomes much easier. Unfortunately, society would rather prop up the free market with capital than invest in public works which benefit more than corporations and shareholders.

Good points, but we also need to quantify the risks posed by human drivers in similar situations. Getting "similar situations" is hard, but not impossible: aircraft industry builds faithful sims where people can respond to various stimuli (or lack thereof for hours after which trouble comes).

As it is, we bash every crash and failure of such cars and may prohibit those from public roads while statistically they might be making our lives safer, not more dangerous. My 2c.

I see what you're getting at, but there is a certain amount of cognitive dissonance at play here. If a person driving a car strikes a pedestrian, there may be a grey area as to who was at fault. What was the speed of the driver? Was the driver impaired? Was the pedestrian impaired? Was the driver's view obstructed, was the pedestrians view obstructed? Etc, etc.

But when a system that is designed to autonomously detect infinite, non-discrete, random variables fails prevent a collision/incident, you have a failure. There is no grey area, Y or N. The hope is, the system is smart enough to determine exactly 'why' there was a failure (i.e. the system recognizes the input, a pedestrian in this case, but was not able to prevent collision due to the constraints of physics, or without a nominal increase for concurrent accidents). Still a failure, albeit a failure with a greater snapshot of heuristics and causality.

You're getting stuck up in pedantry when only one thing matters: Do AI drivers kill fewer pedestrians than human drivers?

I've never understood techno-optimists on this point.

If Uber has such amazing technology that avoids accidents, they could deploy them as accident-avoidance for regular drivers. They could give normal driving control to the humans, and take over only if there is a potential of accident.

If you argue that these driver assistance technologies already exist, then you better not be comparing your magical AI on supersafe cars with sunny climate on well marked highways to the average driver on the average vehicle under average climate on average roads.

That is a good point, especially when considering that modern cars have semi-autonomous controls which are likely to actually be effective in preventing ‘human’ failures, while still maintaining the UX of a non-autonomous vehicle.

Another point to consider, is that the actual experience of autonomous driving may increase the likelihood for ‘manual intervention’ failures due to the system being able to react correctly most of the time!

Sure, but do they? Can we really know with such different sample sizes?
Re:Uber’s self-driving car could not detect pedestrians outs... by romwell on Wednesday November 06, 2019 @08:50PM (#21469667)
Regarding sample sizes.

Say, you claim your product works, on the average, for 80 years before breaking.

I believe you, buy it, and it promptly breaks within 2 years of operation.

Maybe I was unlucky. But high more likely, you were bullshitting me.

That's what we have here.

Human death rate: 1 death / 80 million miles

Uber's death rate: 1 death after 2 million miles

So yes, we can make judgement calls.

All evidence points to nope.

Citation needed. This is my argument. Unless you are working for Uber/Tesla/Waymo where is the data? I'd even be satisfied with seeing incidents where the system successfully avoided collisions, at least as a baseline. How do regression lines trend in comparison to non-autonomous cars considering scale?

>Citation needed.

Sure!

Traffic fatalities in the US, human drivers: 1.25 deaths per 100 million vehicle miles [1]https://en.wikipedia.org/wiki/Transportation_safety_in_the_U...

Uber's self-driving car fatality rate: 1 death per 2 million miles[2]

That is, Uber's state-of-the-art is an order of magnitude worse than human drivers.

I know, you'll complain about small sample size. The thing is, assuming Uber's cars match humans, the chances of a collision happening only after 2 million miles are very small, like pulling an ace of spades out of a shuffled deck of cards.

The point is, we do have the data, and the data does not support optimistic beliefs.

I'm pretty sure if they were better than humans by any real statistical margin they would be trumpeting that in press releases. The fact that they work so hard to maintain such secrecy- only revealing data that they are legally mandated to- suggests that they, the people must familiar with the system performance, think it is inadequate.

In essence, because the people who control the data have an interest in revealing data that is superior to human performance, the lack of conclusive data on this leads to an inference that it isn't.

Without simultaneously reporting the identical data for human driven vehicles in a complete, accurate, and globally comprehensive way there is little that can be done with such data except use it to make political attacks on the technology.

As comparison: every single battery electric vehicle that has a fire is widely reported and disclaimed, impugning the technology as unsafe. The 10s of thousands of flammable fueled vehicle fires are completely unreported in the media.

A brief look at https://www.nhtsa.gov/ reveals that more data is available than I thought, along with a roadmap to full automation (https://www.nhtsa.gov/technology-innovation/automated-vehicl...). I'm glad this is being looked at, and it seems that they are in favor of automation. That being said, the data is there for comparison/analysis. One major benefit of autonomous vehicles is that they are certainly better reporters than humans. They need not rely on the fallible memories of human drivers when data from sensors, cameras, internal system monitoring etc is out there living in the data-center. A complete snapshot of an event for replay removes any uncertainty from the equation. Simply put, these systems are designed to provide optimal data that should be captured for analysis. I am not a Luddite here, I think that it is possible for machines to be more effective drivers than humans. As a consumer/pedestrian however, I am skeptical of any claims without actionable (open) data being provided.
