oldgradstudent··on "Never, ever, no matter what, go to a timeshare presentation"
A former colleague of mine loved going to these type of events.

He enjoyed toying with the reps, almost agreeing to sign, then in the last moment suddenly asking a hard question. Watching them apply all their dirty tricks.

He and his wife would go out to such event once in a while and come back with stories to tell.

oldgradstudent··on Cruise confirms robotaxis rely on human assistance every 4 to 5 miles
Gets stuck in the middle of the lane. Often multiple cars at once.
oldgradstudent··on Cruise recalls all of its self driving cars to fix their programming
It's even worse.

It first reached a full stop after hitting the pedestrian.

Only then the car decided to pull over and dragged the pedestrian, ending with it's wheel on the pedestrian.

This is reportedly what caused the major injuries.

Until the leaks started Cruise had zero transparency.

Even when reporting was mandated, they twisted the definitions to make them meaningless.

Cruise cars spend 2-4% of the time under remote assistance, but Cruise reported one disengagement per 95,000 miles in their most recent DMV report.

Koopman is great, I've been considering starting a fan club ever since I've heard him on some podcast a few years ago.

BTW, just recently I needed to choose a CRC polynomial and discovered his work on that field as well.

Yeah, thanks. Got distracted.

They barely drove a few million miles in ideal conditions and where children are relatively uncommon.

Edit: removed a Cruise incident.

oldgradstudent··on Cruise Knew Its Self-Driving Cars Had Problems Recognizing Children
They were not able to recognize them as kids rather than generic humans. Kids behave differently and more erratically.

The details are not that imporant. The main point is that they were aware they were couldn't match human performance on kid safety yet still put their cars on the street. all while talking about the terrible toll of car crashes on children.

> Two months ago, Kyle Vogt, the chief executive of Cruise, choked up as he recounted how a driver had killed a 4-year-old girl in a stroller at a San Francisco intersection. “It barely made the news,” he said, pausing to collect himself. “Sorry. I get emotional.”

> So yes let’s set these absurdly high standards, while we leave children to fend for themselves against human drivers that have met non-existent standards on a continual basis.

Looks like Cruise was well aware they are not even close to the average human driver when it comes to handling kids.

They didn't bother to tell us about that.

We'll see about Waymo's safety culture after their first serious incident.

Transparency is sorely lacking in this sector.

oldgradstudent··on Cruise Knew Its Self-Driving Cars Had Problems Recognizing Children
> According to one safety memo, Cruise began operating fewer driverless cars during daytime hours to avoid encountering children, a move it deemed effective at mitigating the overall risk without fixing the underlying technical problem. In August, Cruise announced the cuts to daytime ride operations in San Francisco but made no mention of its attempt to lower risk to local children.

Edit: looks like Cruise is not long for this world. Insiders seem to have lost faith and are starting to leak. I'd bet it simply cannot withstand any serious scrutiny into its safety levels, practices, and culture.

oldgradstudent··on GM's Cruise alleged to rely on human operators to achieve "autonomous" driving
> I agree, but if we're doing this, lets also make Human Drivers do this, and for real parity, make sure all human drivers are kitted out with all the same cameras and logging systems we ask of from autonomous car companies, auto submitted to the DMV.

Human drivers are the status quo. Once you consistently show that self driving can do better there would be a point in discussing that.

The problem is that you can't because such technology simply does not exist. There is no perception technology that is reliable enough. There is no prediction technology that is reliable enough.

To me it is obvious that Cruise and Waymo (and their likes) simply cannot withstand any serious scrutiny.

> P.S: If the claim is that a one-time DMV driving test is enough, then that should be enough for autonomous cars as well (I'm not making that claim)

The DMV driving test is just one element. We also know how human develop and what skills they acquire and when.

We don't let them drive until they're 15-17 (depending on local laws) because they lack certain abilities earlier than that. For example, humans acquire object permanance at around 24 months.

The Cruise incident shows that Cruise vehicles lack object permanance. They should not be elegible even for a DMV appointment.

oldgradstudent··on GM's Cruise alleged to rely on human operators to achieve "autonomous" driving
> We don't have the data to claim this, this confidently, and the only way to get the data is let the experiment keep running in the real world (only place that matters).

How about we start with something simpler: have Waymo, Cruise and their likes produce a rigorous safety case[1] arguing why their vehicles are safe.

Once the safety case is in the open, we can also evaluate how well their system satisfy the claims in the safety case, and if the assumption do not hold, we can stop the experiment.

They are experimenting on humans. The usual requirement is informed consent.

> I'm not sure why you're comparing fatality miles vs no-fatality-accident-that-cruise-didn't-cause miles

Because it's not that everyone ignores road fatalities, it's just that cruise hasn't driven (in terms of miles amd conditions) nowhere near to what might result in a fatality with human drivers.

Even then, in an incident they've not initiated, they've unnecessariliy made an existing bad situation far far worse.

> (i.e. we have no idea how safe Cruise would be if there were no human drivers on the road)

Self-driving cars have to exist in a world with human drivers, pedestrians, and the rest of reality. No one cares how well Cruise does in a sterile environment.

They should not only not cause incidents, they should also not make existing incidents far worse because of terrible decisions.

oldgradstudent··on GM's Cruise alleged to rely on human operators to achieve "autonomous" driving
In the US on average, there's a fatality every ~85 million miles driven, and that's an average that includes motorcyclists without helmets, old unsafe unmaintained cars, the worst roads, and adverse weather conditions.

Cruise barely drove a few million miles with new modern cars, good weather, the ability to choose optimal roads and weather, and yet it already severely injured a pedestrian.

We can argue about Cruise hitting the pedestrian, but reportedly, the major injuries were caused by Cruise, after reaching a complete stop, deciding it has to clear the road, and dragging the screaming pedestrian and ending with the axle over the pedestrian.

LOL.

That's only the operation staff.

oldgradstudent··on Cruise Grew Fast and Angered Regulators. Now It's Dealing with the Fallout
> Half of Cruise’s 400 cars were in San Francisco when the driverless operations were stopped. Those vehicles were supported by a vast operations staff, with 1.5 workers per vehicle. The workers intervened to assist the company’s vehicles every 2.5 to five miles, according to two people familiar with is operations. In other words, they frequently had to do something to remotely control a car after receiving a cellular signal that it was having problems.

oldgradstudent··on California suspends Cruise's autonomous vehicle deployment
They showed a video of the crash without the part where they dragged the pedestrian for 20 feet, claiming it was the full video of the incident.

The DMV was not aware of that until notified by another government agency that was investigating the incident.

oldgradstudent··on California suspends Cruise's autonomous vehicle deployment
That's a press release.

Why is anyone paying attention to it?

In their original press release they didn't even mention dragging the pedestrian. Here they've only mentioned it because they were caught red handed by the DMV.

oldgradstudent··on California suspends Cruise's autonomous vehicle deployment
> Reading this, it rather seems like the AV wasn't at fault in the accident itself and handled itself well.

Probably because you're reading their press release. Their previous press release was even more convincing - they somehow forgot to mention the part about draggin the pedestrian at the time.

Here they somehow forget to mention the car has already accellerated to 18mph while a pedestrian was still crossing the road.

oldgradstudent··on California suspends Cruise's autonomous vehicle deployment
They also somehow, cough, forgot, cough, to include this part in the video they've shown to reporters and the DMV.

Humans can thrive on meat alone without any problem.

No fiber and no phytonutrients. The supposed benefits of both are basically hypotheses with really crappy observational data to support them.

Sucrose is effectively 50% fructose.

And the supposed benefits of fruits are pretty much non-existent.
