I considered this before posting, but I think that human disengagements are an important supervisory signal for the model. You can’t hire enough safety drivers to scale this process and releasing it is the fastest way to get there. Simulations are not going to get you all the way because you can’t simulate the real world perfectly. Do you have any thoughts on how to develop this without releasing it?

I am sorry but I sincerely hope you are never made responsible for the release of anything remotely safety-critical.

Please re-read what you wrote. You are saying that because a business does not have enough money/resources to scale a process in real-world conditions that the solution is to release something and verifying in the real-world, on a public road, risking real human lifes?

If you don't have enough money to test it then you don't have an actual product/business.

Wild to infer that from someone asking a hypothetical ethical question.

Why are so many on this site so aggro?

Had to google aggro, no aggression intended at all, but I frankly found the severity of GP question too scary to be considered.

To me this is not someone asking a hypothetical but someone who is aware that what they are about to write is controversial yet are still considering it to be the best way forward. I happened to strongly disagree with that.

If there is clear evidence that these cars would have lower fatality rates than human drivers (I don't think this evidence currently exists), then holding off release to continue development is potentially a moral bad, for the same reason that we end clinical trials early when they demonstrate clear life-saving potential that would save lives in the control group.

I don't think it is morally reprehensible to ask what other people's intuition around this problem is.

> Is it worth killing n random people, for a uncalculated and unknowable chance of saving n+m lives in the future. The pool of people randomly selected to die have not volunteered or consented to be part of this project. There are ways to achieve the same lifesaving endgoal without the upfront sacrifice of lives.

The part which really strikes me as morally reprehensible is where the companies are saving money on test drivers and controlled test environments and externalizing those costs onto every other driver sharing the road with their training data collectors

This reasoning renders any governmental policy change of any sort impermissible.

It isn't coherent to apply these forms of deontological ethics to state action - a random set of people will die with both state action and omission of action, I see no reason why not to pick the option with the smaller expected number of deaths.

But this is all besides my original point: this is a legitimate moral debate to have and the rhetoric used by the above commentator was entirely uncalled for.

Hey man, I understand this is a sensitive topic that people have strong opinions on so proposing something that sounds controversial can trigger a lot of assumed conclusions. Can we take a step back for a sec?

First, before we assume that it is inherently risky to release this tech in the public, let's consider where the risk comes from.

There is some risk caused by the inadequacy of the technology to handle certain edge cases. This can result in the vehicle making dangerous maneuvers. However this risk is mitigated by allowing the driver to control the car as soon as the car does something wrong. I'd imagine that the vast majority of errors like this can be handled safely by a human driver who's vigilant and has control of the car.

Some unknown proportion of these might be unavoidable accidents caused by the self-driving software that a human would have probably made too (e.g. a deer running onto the road).

Another possibility is that the self-driving car causes an error that a human might otherwise not have caused and could not have been avoided by a human taking control. If you group the latter two cases together, and the accident rate is lower than that of the driver without self-driving enabled, you could argue that it has a positive impact.

The other source of error is human error. Some argue that self-driving makes people complacent and they might not be as vigilant as if they were operating the vehicle themselves. I think companies are trying to address this too by implementing driver monitoring systems, however this is completely avoidable by the passenger and its a stretch to say that self-driving cars are risking human lives because of this.

Hopefully I have conveyed the reasons why I don't think public testing is necessarily inherently risking human lives (of course this is dependent on the state of the tech being released). I'm sure you understand that every company has a limited runway and a window of opportunity to scale their technology. I am 100% with you on making sure that the product doesn't risk people's lives recklessly. However, I think the optics of this make it seem like far more lives are at risk than reality. I'm open to changing my mind as more information about the safety of the tech comes out but I am not de facto against it for the reasons I mentioned above.

Waymo appears to disagree with you, they ran tests with safety drivers and in controlled conditions for a very long time, and they eventually got to the point where there are customers riding in unmanned taxis. Tesla is just applying a "move fast and break things" approach to pedestrians' lives in order to satisfy shareholder interests and executive egos. They're not the only ones, as we saw from Uber's absolutely shameful performance that eventually lead to a death (safety driver involved but not solely responsible, of course)
I was under the impression that while Waymo did some tests unsupervised, most of the rides that non-employees can hail still have a supervisor. Is that not true?
I've seen youtube videos of unsupervised waymo cab rides, and when it got stuck in one they sent techs out to rescue it. It's probably still uncommon.
