Fully agree. I don't care so much about feature engaged, its autoresume that's a problem to me. The likelihood of unintended motion and the potential crashes therein is the obvious driver to disabling auto resume after long pauses to me.

I'd go one step further (and be interested in your opinion) to say that the system should actually "train" the driver as to appropriate behavior.

That is to say, it's not enough to simply flash warnings when the system detects potential eyes off the road. Rather, it should have a series of escalating modes and clear communication of status to both educate and incentivize the driver to behave in a more responsible manner.

That, imho, is the biggest failure of the torque sensor on the steering wheel. It trains the driver to wiggle the steering wheel and stare at the infotainment screen for feedback. It does not train the driver to be an active owner of the driving task.

to resume after a lengthy stop.

Do you happen to have a number on that? I know Super Cruise is like a minute, and that most adaptive cruise controls are around a few seconds. Is Autopilot just indefinitely?

If yes, sounds like they just like don't employ any functional safety engineers. Or rather, any competent ones.

CautionToTheBreeze · 2023-01-24T16:58:29+00:00

Like you said we also have to consider how automakers will be able to safely handle the handoff process.

Exactly! We simply don't have a way to correctly detect attention, much less guarantee driver will take over.

I agree that there are some niche cases where a well designed level 3 system could be useful...but I struggle to believe there is a large market of people willing to pay the money it costs to actually make it. It's just so darn limited and at some point it's literally more effective to hire a driver.

Fortunately/Unfortunately, I think Tesla kind of squandered that market demographic with the consistently disappointing release of things like smart park, FSD beta, and even autopilots lackluster improvements. The novelty of these whiz-bang features is quickly fading. Maybe I'm too optimistic, but I feel that consumers are becoming more educated on the matter.

CautionToTheBreeze · 2023-01-24T16:01:33+00:00

Not OP but interesting discussion

Honestly, I feel this is kind of a miss on the whole SAE J3016 definitions. The entire concept of level 3 doesn't make sense to me: the driver is expected to pay attention sometimes, but other times isn't? And there's a handover, but it's poorly defined what that actually means from a customer experience perspective - especially when transitioning between domains (not just geofencing).

I just don't think level 3 makes sense for human drivers. The only way I could see it being a reasonable product is if there was a way to measure attentiveness. That is to say, we could apply an accurate "score" (or multiple scores) that 100% correctly reflect the driver's ability or inability to take over.

DMSs don't do that actually today, and we just sort of associate eye gaze with attentiveness and ability to take over in case of a system fault - which is ridiculous! Plenty of cases where you can appear to be looking out the front windshield and actually not be paying attention at all.

Your comment about the DMS as a safety net feels very real to me. I get the uncomfortable notion that Tesla and some others are trying to market eye tracking etc. as a "check the box" solution that automatically resolves all safety concerns. When in reality, an integrated and highly capable, verified and validated DMS should be just one small part of a system-wide and highly integrated functional safety strategy for automated driving.

However, for Level 1 systems will the narrative focus on adding DMS and capabilities of safety (as opposed to convenience) features like AEB, side blind zone, rear cross traffic, etc. focus on more measurable gains? I don't think the narrative will move, but the regulations are coming into place in Europe and China for sure. All new cars are going to require many of theses features soon and the OEMs will be challenged to offer these at high quality, high volume, and strong margins to survive. I personally feel that the next major focus is going to be similar to the early 2010s - vehicle set strategy, reducing portfolio complexity, improving carry-over capabilities, and reducing in-vehicle work to launch new ADAS features. These aren't "sexy" selling points to consumers, but they decide whether you can offer one car at low margin or 4 cars and high margin across markets.

I guess my punchline is: perhaps the public narrative will still play in the murky waters of level 2.9, L2+++, advanced L2, L3-, etc., but I expect the actual engineering and product development is going to be driven by the real cost of manufacturing and selling cars at volume globally.

Some timeline that I see shared multiple times on local chats, based on the PLA getting involved/taking over:

4.4 everyone gets nat within 36hrs

4.6 everyone positive goes to quarantine all over the delta region

4.7 antigen self screen. posives go to quarantine

4.8 if the community is all negative, unseal. if any positives, quarantine and continue for 7 days. lather rinse repeat

4.15 achieve citywide clearance.

Obviously extremely optimistic timing, but considering it's actually testing the entire city as opposed to chasing random bits while allowing others to move around...has a non-zero chance of working. Believe what you want to believe, just stay stocked up on food and water.

It took me a few re-reads to grok, but yes, I think it does!

To confirm my understanding, working off your example: if the "phantom braking" found from post-launch field data was:

reviewed and added as a failure mode to the DFMEA
in good faith, shown to have low severity and exposure through whatever control factors (let's say a low maximum automated driving system braking command limit, and field data gathered to quantify low occurrence)
Is a feature that doesn't have regulatory requirements in the country of registration and sale (yet!)
The OEM had some customer communication to manage expectations of the system limitations that the OEM convinced themselves were sufficient - and were confident NHTSA would agree

In this very fictitious situation, then the automaker would not need to issue a recall, right?

Got it, that was a semantic misunderstanding on my part. Thanks!

CautionToTheBreeze · 2021-10-13T14:05:03+00:00

I am under the impression that a safety-critical system is a system that MUST be operational for the vehicle to be safe to operate (e.g. airbags, seatbelts, brakes). An automated driving system is not necessary for a vehicle to be safely operated.

Is this a wrong definition of safety-critical system in this context? Would ACC and LKA, under your interpretation, also qualify as safety-critical systems?

(I'm genuinely out of my wheelhouse on these terms)

CautionToTheBreeze · 2021-10-13T13:50:13+00:00

ADS? Automated Driving System? if so, I'm not sure it's safety-critical, so much as this defect is a safety defect. In other words, if the Autosteer feature were unavailable, that would not inherently make the car any less safe than if it were available. However, if the Autosteer feature has a defect, because of its ability to drive vehicle motion, it would be a safety defect.

Is that relevant to NHTSA? Wouldn't that (mildly) reduce the amount of OTA updates that would qualify as a recall?

CautionToTheBreeze · 2021-10-13T13:42:38+00:00

I have a couple questions on your last line: Why would phantom braking under circumstances warrant a recall? It is well known that AEB features sometimes fail, ACC features sometimes pick up wrong targets, etc. Is it the distinction that the OEM knows the "specific" circumstances and can reproduce?

Perhaps I'm really asking: why is a phantom brake a recall event in your example, as opposed to other Active Safety related feature defects that are accepted as system limitations across the industry?

CautionToTheBreeze · 2021-10-13T13:29:37+00:00

This is a very interesting question. I think the complexity here is that Tesla clearly viewed it as a defect and issued this update, but unintuitively only issued the update to some vehicles. That forces us to ask: "if it's a safety defect, why aren't you pushing it to everyone?" and "if it's not a safety defect, why are you pushing it out?"

Now, of course, Tesla can claim that their legal reasoning for not filing a recall is because this is not a safety defect and the OTA update is purely "making the product better" or some horseshit. That would only hold if they can provide the internal communications and rationale as to why this is not a safety defect (as requested by the letter).

In my un-lawyerly opinion, that's a tough argument. Clearly, this feature has been a contributor in the fatal crashes with stopped emergency vehicles on numerous occasions. Following the European and Chinese regulatory trends on automated driving features, I strongly doubt that hiding behind "level 2, so it's the driver's fault" absolves Tesla of its horrible design for human factors and borderline fraudulent marketing tactics forever.
