If you can set a guaranteed maximum on the delays (regardless of what those limits are), you're hard real-time by definition. The horror is that they weren't building a system that could support those guarantees.
I see, thanks. What if say, a system is written against an indeterminate timed GC like say, Azul or Go's, but code is written in a way that proves GC times never exceed X, whether by theory or stress testing. Is this still seen as 'unguaranteed'?

Genuinely curious: how would you even go about advancing autonomous driving without testing it in the streets? I'm absolutely certain that they've attempted to simulate millions of hours of driving, yet this odd behavior happened in real life, which now can be studied and fixed. If we never had the software on the wild, how would you ever really test it?
>Genuinely curious: how would you even go about advancing autonomous driving without testing it in the streets? Genuine response: 1 don't let customers do the testing, especially if you don't train them (I mean real training about failures not PR videos and tweets and some small letter manual with disclaimers) 2 use employees, train drivers to test, have some cameras to check the driver to make sure he pays attention…

99% perfect is not good enough, it's horrifyingly bad for a car on public roads. When I drive, I don't spend 1 minute plowing into pedestrians for every 1 hour and 39 minutes I spend driving normally. If a FSD Tesla spends just 99% of its time doing boring, non-click-worthy things, that is itself interesting in how dangerous it is. To your point, I'm definitely interested in knowing how many minutes of boring driving…
99% is a an very rough colloquial estimate meaning 'the vast majority of the time' to drive the point. Could well be 99.999999%. What really matters is how it compares with human performance, I don't have data to do that comparison. The only ones that can make the comparison are Tesla, modulo believing data from a megacorp in the wake of the VW scandal.
FSD should not be allowed on the road, or if it is it should be labeled as what it really is: lane assist.

Of course it's not fine in that sense. What I mean is that you don't see a headline on news outlets or twitter hashtags trending for every drunk driver fatality or crash that happens. Which for me tells that collectively, we are fine with it. We accept it as ordinary, as crazy as it may be.
I regularly see "traffic collision kills [person or people]" stories in my local newspaper. I don't know if it's every one, it might be restricted to the extremely stupid (wrong-way on the highway, drunk, or excessively-high-speed) but "someone got killed" is certainly a common story in the news here. I've certainly seen many more local "person dies in car accident" non-brand-related stories than "person dies in Tesl…

I've made this argument here a few times and am always shot down, but I think its important to highlight that the airline industry has an extremely robust history of automation and HCI in critical transportation scenarios and it seems to me that all the lessons that we have learned have been chucked out the window with self-driving cars. Being able to effectively reason about what the automation is doing is such an i…
Hi, aerospace software engineer and flight instructor here. I think you get shot down because the problems just aren't comparable. While I agree that there may be some philosophical transfer from aircraft automation, the environments are so radically different that it's difficult to imagine any substantial technological transfer. Aircraft operate in an extremely controlled environment that is almost embarrassingly si…
I'm with you that they are super different, and that the auto case is likely much, much harder. But I see that and can't help but think that the path we should be following here is one with a much greater and healthy skepticism (and far greater human agency) in this automation journey than we are currently thinking is needed.

Something I do not understand: there are keys difference between automation in e.g. aircraft, and what Tesla at al are failing at, e.g., how constrained the environment is; and what the exposure is to anomalous conditions is; and what the opportunity window usually is to turn control back over to a human. The thing I don't understand is, we have a much more comparable environment in ground travel: federal highways. I…
Even lower-level automation for highway driving would be super useful. I would appreciate a simple "keep-distance-wrt-speed" function for bumper-to-bumper situations. Where worst case scenario, you rear-end a car at relatively low speeds. I'd happily keep control over steering in this situation and just keep my foot over the brake, though lane-keep assist would probably be handy here as well. A couple radar sensors/c…
A more advanced problem would be safely stopping in case the driver falls asleep/looses consciousness, eg. on a highway. that short amount of self-driving is less error-prone than the alternative.

>On my first Tesla, autopilot would regularly try to kill you by running you into a gore point or median (literally once per trip on my usual commute) And people paid money for this privilege?
To be fair, it still felt like magic. My car would drive me 20 miles without me really having to do anything, other than make sure it didn't kill me at an interchange. And I'm now trying to remember, but I think autopilot was initially free (or at least was included with every car I looked at, so it didn't seem like an extra fee). Auotpilot is now standard on all Teslas, but FSD is an extra $10k, which IMO is a joke.
Also, the problem is “easy” for the general case, but the edge cases are almost singularity-requiring. The former is robot vacuum level, the latter is out of our reach for now.

> Being able to effectively reason about what the automation is doing is such an important part of why these technologies have been so successful in flight, and examples like this illustrate how far off we are to something like that in cars. Is that actually the case, though? I would hope, although perhaps I'm mistaken, that the developers of the actual self-driving systems would be able to effectively reason about w…

#330Maximise the video and watch the left hand HUD pane from 0:10 to 0:11. The dotted black line coming from the front of the car (which I am assuming is the intended route) quickly snaps from straight ahead, to a hair pin right, to a normal right turn. Ignoring the fact that the right turn happened to be into a pedestrian crossing with people on it - what was the car even trying to do? The sat-nav shows it should have j…
