"We believe it’s important for Mastodon to be good as a product on its own merits, and not just because of its ideology. If we only attract people who already care about decentralization, our ability to make decentralization mainstream becomes that much harder."

adamjcook,

@kentindell @molly0xfff Yeah. I agree. I miss those a lot.

But, clearly, not in the cards for a while.

Learning that these decentralized networks have a ton of more foundational work to do lately.

I was thinking of trying to get together a Discord chat/voice channel in the meantime for the old “Automotive Safety Twitter” group.

I don’t know.

I am seeing posts from @DeepDishSwift which is the first conference where I am seeing most attendees posting on . That’s a welcome milestone.

adamjcook,

@brennansv @DeepDishSwift Cool!

I really wish we could get something like that here in one day.

adamjcook,

@brennansv @DeepDishSwift Oh. I got some irons in the fire over here. 😉

You may not be that far off.

adamjcook,

@brennansv @DeepDishSwift Great advice. Thanks.

I am thinking it will be something more local to start off… more community focused… more beginner focused.

We will see where it goes from there.

Still, we are getting some attention lately from other tech corners. 2023 will be here this year.

Hope to announce something soon.

adamjcook,

@brennansv Very cool.

Thanks for the insights!

How much money do you think Cruise/Waymo etc have thrown at London Breed and other SF gov't officials? That these vehicles are still allowed to be on public roads is some incredible regulatory capture.

adamjcook,

@mattmangels Frankly, the regulations/laws for automated driving systems in the State of California are so hopelessly weak that no palm greasing is necessary.

Always were.

It is basically self-certification under the guise of actual regulation.

I mean... on another closely-related topic... California had passed a law that went into effect this year specifically designed to rein in 's deceptive "full-self driving" product name.

Tesla just ignored it, near as I can tell.

adamjcook,

@chema @mattmangels It’s that and it’s really just a continuation of effectively having zero automotive regulations in the US on a federal level.

The , the federal agency responsible for highway and vehicle safety, has spend decades and countless resources to construct a public image of robust regulation, while the truth is entirely the opposite.

I have written about this extensively in the past: https://www.reddit.com/r/RealTesla/comments/zti9f8/the_infamous_nhtsa/?utm_source=share&utm_medium=ios_app&utm_name=ioscss&utm_content=2&utm_term=1

    adamjcook,

    @ianbetteridge The whole thing is just like the program all over again.

    To the letter.

    No safety systems lifecycle.

    No upfront failure mode analysis.

    No downstream considerations for indirect harm.

    Vague and questionable technical value.

    Zero systems safety value.

    is just wholesale "wingin' it" while, once again, attempting to palm off 's would-be responsibilities onto the public - a considerable, short-term time and money saver.

    adamjcook,

    @ianbetteridge I hope so... and, hopefully, not just from the perspective of Musk's detestable belief system and constant lies, but because this character is literally tearing up decades of hard-fought safety-critical systems norms and knowledge.

    And he is doing so wantonly.

    The is a deeply troubled agency and I think the "reforms", whatever they may be after the 737 MAX scandal, will come up hopelessly short.

    Sadly, the FAA is probably the most robust agency under the US Department of Transportation.

    Agencies like the (the agency responsible for highway and vehicle safety) might as well not even exist.

    Secretary Buttigieg has been profoundly disappointing on this front.

    Secretary Buttigieg was one of the first candidates that I can recall in recent memory that actually made roadway and transportation safety a centerpiece of his presidential primary campaign.

    These topics are hardly ever even mentioned on the campaign trial!

    Elaine Chao, Trump's pick for Secretary of Transportation, did enormous damage to the and its sub-agencies and Biden and Buttigieg needed to get the ball rolling from Day 1.

    Did not happen.

    adamjcook,

    It took the Administration nearly a year to nominate Steven Cliff as Administrator - an unacceptable amount of wasted time.

    And Steven Cliff left after three whole months!

    Today, the NHTSA is without a permanent administrator.

    The public is being constantly misled that there is a strong regulator backing the safety fitness of your vehicle and of the roads that you use.

    adamjcook,

    Let us check in on the current state of leadership, shall we?

    I have no comment.

    What a mess.

    @SpaceLifeForm It is not happening at all.

    Ok. So recently, had published an "Impact Report" which contained a slide presenting some "data" that their and products "enhance safety".

    And one article and one Twitter thread caught my eye in scrutinizing these numbers.

    https://www.forbes.com/sites/bradtempleton/2023/04/26/tesla-again-paints-a-very-misleading-story-with-their-crash-data/

    https://twitter.com/NoahGoodall/status/1651323363099553793

    While the analyses and arguments in this article and thread are not necessarily wrong, there are more fundamental issues here that need to be surfaced in my view... so let's take a look.

    adamjcook,

    @_dm It is higher level that a statistical analysis, higher level than any particular engineered system.

    It is about where a robust systems safety lifecycle does not exist, the downstream safety dynamics are purely speculative to everyone at any given time.

    There was literally no effort made to avoid unhandled system failure.

    A roll of the dice with human lives.

    That is what Tesla is doing.

    That is what Boeing did.

    That is how they are the same.

    adamjcook,

    @_dm It is more like statistical analysis on endpoint safety is always (or should always be) a secondary concern.

    It is dangerous to breathe a sigh of relief based on some, let's say, extremely low incident rate if there was never an appropriate validation process in place during development and continuously after delivery.

    It is just a ticking time bomb of avoidable death and injury.

    I believe that is another way of saying what you wrote.

    adamjcook,

    @_dm Additionally, specific to collecting roadway safety data, there are more practical issues... which I outlined in a Reddit post some time ago in detail: https://www.reddit.com/r/RealTesla/comments/xqauju/the_no_news_is_good_news_fallacy_of_fsd_beta/?utm_source=share&utm_medium=web2x&context=3

    Public roadways consist of a myriad of interacting components, so 's data, even if we want to assume is being published in Good Faith (*), is at least one-half incomplete anyways.

    (*) Which should never be assumed, for any automaker.

    adamjcook,

    @CrackedWindscreen Yup.

    NCAP programs are deeply problematic for multiple reasons.

    It is essentially used a cover for what should be regulatory rigor, which is totally unacceptable.

    They are not rigorous, not exhaustive and, arguably, not independent assessments.

    They also completely fall apart now that Over-The-Air updates are in the picture.

    adamjcook,

    @CrackedWindscreen No NCAP program I am aware of even incorporates automated driving system assessments in their core ratings… which is simply absurd in 2023.

    There is no sense assessing active safety features if their characteristics change when an automated driving mode is active.

    adamjcook,

    @_dm I think something similar exists in safety-critical systems.

    At some point, during systems validation, there has to be a discussion of numbers, of statistics, of risk.

    Potential systems failures are identified and categorized. Margins of safety are established. And the system is exhaustively exercised under a controlled process to evaluate it.

    This process is continuous (never ends) in all safety-critical systems, as no system can ever be "perfectly safe" at any time.

    adamjcook,

    @_dm Maintaining a systems safety lifecycle is nothing more than a Good Faith acknowledgement that unhandled failure will always exist (even in the best of internal processes) and that there needs to be an efficient "feedback loop" of re-evaluating unhandled failure and determining corrective actions, if any.

    It is indeed very much organic.

    adamjcook,

    @CrackedWindscreen EuroNCAP assesses "active safety features" (as you mentioned, LKAS, AEB as so on).

    To my knowledge, EuroNCAP does not incorporate assessments of automated driving systems (i.e. Highway/Enhanced , FSD Beta and so on).

    But assessing active safety features is moot if, when say is activated, the characteristics of those features change because, say, FSD Beta requires "enhanced" object detection and event response capabilities.

    That is what I meant.

    adamjcook,

    @CrackedWindscreen "Funnily" enough it is all moot when a Over-The-Air update can disqualify any assessment made at any previous time.

    It just all goes back to fully relying on "the word" of the automaker and not actually independently scrutinizing whether or not the automaker has appropriate internal processes at all.

    NCAP covers all of that up with a shallow "star rating" and the public eats it up (understandably so).
