I have formally accepted the CEO job at Cruise once again

This is directly the opposite of what Tesla has mandated their engineers to do, which is to be 100% reliant upon camera systems only.
Somebody at Cruise commented that their intention is to drive down the cost of LIDAR units through economies of scale and better technology.
My personal belief is that the data acquired from LIDAR representing a at-this-moment-in-time snapshot of a vehicle's surroundings is very valuable, and Cruise is probably going down the right path with this.
Relying entirely on cameras only requires the full intellect of a human who can make snap judgments about what's going on in a scene (eg: a pedestrian wearing a black or dark blue jacket who is walking a black or brown labrador retriever across an unmarked crosswalk in Seattle level mid winter rain, at night time, something I literally saw just two nights ago).
Aren't AI models already better at image recognition than humans?
(I'm not suggesting that using LIDAR is not an improvement though).
On some benchmarks, AI models are better at very well defined tasks like image classification (“label this image from a set of 8 labels you’ve seen before”) or object detection (“draw a box around all instances of class X in this image, where X is a very narrowly defined class”) They’re not even close to being able to understand unscene examples and parse out their meaning in a larger context the way humans can. (“Recognize that this object in the road is a human riding some sort of bizarre unicycle he welded himself, then predict how he’s likely to move given the structure of his custom unicycle thing”)
The bottleneck in AVs isn’t “perception” in the sense of image classification and object detection, it’s deeper scene understanding and abstract reasoning.
LIDAR is useful for a ton of other reasons - ground truth depth, high visibility at night, great for localization - and can detect if something’s an obstacle or not without having seen it before (but false positives can be an issue).
Broadly speaking, people who focus on Camera vs LiDAR are missing the mark and don’t understand that the real difference between big AV players and consumer cars is HD maps and remote support.
They are an engineering company, and they will attempt to engineer their way out of the wrong decision (vision only) if they have to in order to deliver.

Tesla is not operating in a way any ethical engineer should tolerate.
Let they who is without engineering sin cast the first stone. Intent and risk appetite is a spectrum.

Death is unavoidable, only preventable short term on a scale. To expect zero deaths is unreasonable.
I won’t buy a GM product and I won’t buy a Tesla product either, happy?
Conflating the two makes it harder to have a conversation about what either actually is or does.
- Autopilot has been "on" during 12 fatal crashes. It's a level 2 driver assist so it isn't "responsible" for those deaths, the driver is. Autopilot data shows it improves safety. Could you explain the unethical part?
- The ignition recall, GM knew it was a problem, and it was. The unethical part is super clear.
These aren't equivalent at all. Actually this highlights the bad faith attacks on Tesla. There are reasonable controversial decisions to be discussed with Tesla's approach. But safety isn't one of them, they have the safest cars on the roads and the lowest crash/fatality rate.
Autodrive is going to force the actual law and the theoretical law to come into sync, otherwise automatic driving cars will cause other issues by sticking to the letter of the law when normal drivers do not.
Companies do it all the time - I'm not even sure it's really lying (as they "collectively" believe they'll be able to do it) but they are willing to pivot when the time is right.
Apple's famously done it - the App Store was never to be at first.
I thought that radar was inside cabin only, to detect kids, etc.?
You could imagine an AESA phased array at 60ghz. But there's a reason you only see those radars on aircraft or military vessels: you need hundreds or thousands of individual transmitters. That's why they cost millions of dollars and draw kilowatts of power, it's not (entirely) defense contractor featherbedding. So where's the cost savings over LIDAR? You can drop the number of radios to save money, but then you don't have meaningfully more resolution then any other automotive single-point radar.
Wouldn't you have to keep that on your books as liability in the same height as the income you had from the sale (as the true cost is not yet known)?
The above is situations I know of offhand hand were my vision isn't up to the task yet I do anyway - because I don't really have other options. If other sensors can outdo me then I want them.
If anything, I think we've seen that computers are much better than humans at making decisions in an ever-expanding set of narrow contexts (eg.: chess, go, protein folding...). It's not so much a matter of "can a computer do it better", it's more a question of "when are we going to figure out how to break down the problem in a way that a computer can solve much better than a human".
But consider how a human or even a dog catches a ball. You can study physics and learn that a ball will follow a parabola when thrown and the the shape of parabola is determined by the velocity as it leaves the throwers hand. But none of that matters. You try and catch a ball. Miss a bunch of times. Practice. And then you get better at it. And then you can catch all manner of things coming at you at various velocities. You can unconsciously predict a ball's path accurately enough to catch it without even knowing any physics. Some people can even rely on their instincts.
This line of thought is moving goal posts, but I think even for people that have some understanding of what AI is, the current state of the art doesn't pass our intuition about all the things a human does to drive a car. And the sorts of mistakes that current self driving makes don't really seem better than a human.
The possibility is not in dispute. Billions of biological organisms do these things everyday.
But this is:
>It's pretty much how your brain solves these sorts of problems too, there's no magic to intuition or human decision-making.
Is it how the brain works?
My ball example isn't about it having a closed solution. If you throw a ball I can track it with my eyes and I know it's going to follow some path. If there is a gust of wind mid flight I can even attempt to make corrections on the fly. Someone with no notion of projectile motion can do this and never come up with the concept of projectile motion.
The "hardware" so to speak figures this out on it's own and the same "system" can be applied to infinitely many problems without prior knowledge and get results. This would be like showing a Tesla some chess games, and then the car realising, this is some sort of game, and then learning how to play or inventing something new to do with the pieces.
The results so far are really terrible compared to our intuition. We have Teslas that drive straight into road barriers and can't predict that a person might reappear after moving behind an obstruction.
This is even more goal post moving and I admit it's very unfair. But I'm not baby sitting a car.
(What is a mystery is the exact way things are wired up, but not the building blocks, and not the general organizational principles.)
Source: I did neuroanatomy in med school (but am not a doctor).
You don't think that's a lot of hand waving? Can you explain why the details wouldn't matter?
I don't want to mislead, there is an incredible amount of stuff we don't know... But we do understand more than most well-informed people think, even people in adjacent fields.
IMO, it's 16+ years of life experience that a computer doesn't get. Sure we train computers on what things likely are in pictures, and where they are on some sort of map. But that gives zero context into the 50,000 other things going on at any moment in a busy street.
I'm in the FSD beta and previously Tesla bounced the radar off the ground and was able to see a few car lengths ahead, vision only, not so much. The effect is when stuck in heavy traffic on surface streets FSD beta will think it should try to go around a lead car that is stopped, not knowing there is a long line of traffic ahead of the lead car. I don't see how they can overcome that issue with vision only, especially given current camera placement.
Could you do this with cameras? Possibly, but it would be a lot of cameras and a lot of mechanical parts—not ideal for a car.
Using more and better sensors is an attempt to compensate for the shallow mental model, so you'd have cars still being 'dumber' than human drivers, but if they're all-knowing, that doesn't matter quite as much.
This is a decent thread that has some visuals, some others have created 3d models demonstrating the blind spots the cameras have.
Not sure how to say it, but try to never do that going forward, please, for your sake and for the sake of the others who share the same road with you. Yes, driving "blind" for one second, maybe two seconds (even though it's uncomfortable for me at this point) from time to time is not the end of the world, particularly if you're driving straight and you had "scanned" the road in front of you beforehand, but driving while "trusting" in others will get you into accidents. Never drive faster than you can see.
For others left wondering what this meant, I think GP meant "I often drive with [the sun] in my eyes at dawn/dusk .."
This is still not 100% safe (especially in blind corners), but this is the minimum One should do.
So as an experiment, at 70 mph I put my face down on the gas tank: I could see the highway lines on either side, but literally nothing ahead. I wanted to see how long I could hold that position without freaking out. Answer: about twenty seconds.
This is far from the only experiment I did back then, I’m lucky to be alive.
And what? Be the lead car of the N-car pileup?
It's real easy to spit out idealized "never/always" type crap on the internet but meatspace is full of nuance and no rules of thumb can save you from having to make judgement calls.
I have driven on the motorway in heavy fog, and like everyone around me I slowed down, and there were no accidents.
Acting like an idiot because you think others will is not a good course of action, especially when you will cause issues to the majority who do not act like idiots.
I really wish transit was better. Even in cities that have what we call good transit, it is still bad enough to too many people drive. (Note, the above issues with human drivers apply to bus and tram drivers.)
there are plenty of cities with great transit, just not in the states
Even in cities you consider to have great transit there is room for improvement.
As far as Tesla goes, I disagree with their decision to remove sensors from their cars, however I also don't think Lidar, Radar, etc. would help all that much. Radar isn't high enough resolution for driving through dense fog, and Lidar doesn't work in fog. Driving in fog is just hard.
To paraphrase XKCD [0] - if you want to cause accidents, there are other failure mechanisms that'd work on humans as well
For whatever reason, Tesla has decided to eschew this hard-earned wisdom, have treated their customers and the general public as an extension of their corporate research lab and their customers and others have paid the price for it with their lives.
During the DUC, contestants competed in an abandoned military base in the middle of the desert. In that environment, the vehicles were outfitted with all matter of flashing lights, emergency stop procedures, and all humans had to clear the area. That's what robot research was like in 2007. And our cars didn't have a verified track record of deaths!
Little did we know at the time, we could've just held the DARPA Urban challenge in the middle of downtown SF. Apparently we wouldn't even have needed to inform the unwitting public that an experiment involving a 2 ton machine that has killed people in the past was taking place in their midst.
Re: dirty windshield. Humans see through those, and we have windshield wipers if visibility is impeded.
I'm still excited about the LIDAR possibilities but vision alone has done a remarkable job.
Not for Tesla. So many interventions. So many situations where the car actively tries to kill the driver and pedestrians.
It's strange to me that Tesla who are building this in the open are criticised for being dishonest. Meanwhile ALL the competitors are closed door private development and some how we should trust them more? In an industry that is known for deceitful behaviour.

That's 1 quarter and the numbers dwarf the combined total of all the competition. It's also a safety report they put out every quarter rather than an adhoc tweet.
How many crashes have occurred on FSD Beta? 0. [1]
Qualitatively, there's no comparison between them. Waymo and cruise are today more than capable of autonomy without a driver in certain circumstances. Tesla still has trouble staying in the lane and doesn't define an ODD or even claim L4 for fair comparison.
For background, I've been in waymo and cruise' vehicles, and ridden with AP. I've only seen FSD in video form.
Tesla publish autopilot data every year. Crashes per mile with AP, without AP, and with Safety assistance features, and show consistent improvement of AP. What do the competitors publish?
You are comparing AP (a traffic aware lane keeping cruise control system) to Waymo (a driverless taxi)? How about FSD Beta vs Waymo how has your experience been there?
By "in public" I mean I can go on YouTube and look up "FSD beta version 8", and "FSD version 10" and see hundreds of videos comparing both unplanned and repeated routes and see improvements and regressions. If I'm in the US I can even get the software myself and try it out (after hurdles)... how much more public could they do it?
https://www.dmv.ca.gov/portal/vehicle-industry-services/auto...
I would love to see disengagement reports for autopilot and FSD. I can't go more than 50 miles without having to takeover for autopilot. Like hitting the gas when it phantom brakes. You can't even use autopilot at night any more due phantom braking issues. I don't even use Navigate on autopilot because it literally tried to kill me on multiple occasions by trying to change lanes into a concrete barrier. Want to see funny. Use smart summon. I wish i could use smart summon and my phones video at the same time.
If your metric is simply public access and videos, waymo and cruise both have public demos available. jjricks has quite a few videos on the former. The latter is too new and small a program to have much content yet.
> They also don't have professional testers like cruise, waymo, etc do validating releases.
Source? From my understanding they rollout releases to employees first (I assume a subset of those are professional testers). Then to beta testers. There have been a couple of releases that have been halted that lend credence to that.
> They also don't publish FSD data, and their AP numbers are essentially useless for determining actual safety
So is this because you can't see detailed data of their in-progress beta software? Could you show me the beta stats of Waymo/Cruise? Where are they published? Tesla aren't operating any robotaxis - so it's clearly not a finished piece of software is it?
On the AP front, why is the AP data useless? Which data do you need that is missing?

Let’s try a diverse set of strategies and see which one wins in the real world. Nobody knows for sure at this point.
Unstructured learning on Image+Text pairs has exploded and set STOTA on benchmark across the field. While the data coming from LIDAR may be better. There is no where near the amount of LIDAR data in the world. Images and cameras have the advantage here where internet is full of weakly labeled data that turns out to be the key for building model backbones that you can retrain for downstream tasks.
About 2/3rds down the page features 'Object tracking' and 'Robotic control'
For example, if a a car is stopped at a red light and it sees a child across the street running and the child runs behind a truck it will take her 5 seconds to get past at her last observed rate of speed, and the light turns green at a moment when the car would hit the child as she emerges from behind the truck (given the preceding) as it drives by the truck, do any ML systems have the ability to predict this?
People would likely be cautious if they saw the same scene, and would approach slowly. I don't think that current ML systems are able to do that, but would like to hear some informed opinions.
Both of those reasons are of course flimsy, if true: form cannot always come before function.
I've always read it as Tesla trying to do a paradigm leap. It seems everyone in self-driving knows you can do it pretty well with a huge variety of sensors, but what if you got extremely good at only camera-based then added in the new sensors.
Basically, if you can establish that the very worst case works, you can add in more sensors to go beyond that and have the cars become superhuman rather than having to depend on all sensors to consistently be working to have a safe vehicle.
I’m not sure how valid an assumption that is, they could wind up just adding complexity and creating noise.
And what if the best answer is being extremely good at lidar-only and then adding in cameras on top.
now is a terrible time to buy a new Tesla car.
But I do realize not everybody can wait it outI think that's debatable. There are plenty of stories of trying to force an outcome of a big software project and things not going as expected.

Naked cameras jutting out are no better.
I agree that LIDAR is valuable and hope all these companies are all able make safe cars with their tech stacks.
Is there some cost prohibitive licensing on it that affects adoption the way e-ink patents have limited product creation?
Such incredible confidence in that statement that there is not even a hint or need to offer up any evidence or anything at all. HN is amazing. Dunning Kruger rules here.
Dan Amman’s original edict to Cruise was to Beat Uber. Uber was not just disruptive in 2016, but they really wanted everyone to feel the size of their ambition. E.g. they placed an order for 100,000 Mercedes S-Classes that ATG was going to then equip. Uber could raise billions easily, and they were culturally reckless, so the OEMs thought them a threat.
When Dan Amman took over, his pay package showed he very much wanted to be a Silicon Valley billionaire (see S-1 docs) who saved GM. And he had history with Mary. To Kyle, Mary is much closer to a boss, but to Dan, Mary is more of a colleague.
Fast forward to today and the self-driving landscape has changed a ton. Uber barfed all over themselves and COVID has changed the world. Dan Amman no longer had a case for making him a SV billionaire, and he never was able to fix Cruise’s culture problems* anyway.
So the change makes a ton of sense, and I’m sure Dan will find some other way to become as rich as sama or Justin Kan. Dan has already done a ton for GM and he’s good at what he does.
* I left Cruise a while ago and while Kyle hired a lot of good people, he also hired a ton of jerks. In some cases he did it personally. I have four different stalkers from Cruise, one who apparently slid into a panel and got me denied a job last year. Kyle, while I do think you’re the best CEO for Cruise right now, you created some culture problems that have caused lasting effects. Focus on what customers want and let the engineers get their job done.
They work without synchronisation to the cars driving next to you.
Turns out it didn't work well. GM learned the hard way the founder was the best CEO of Cruise. There's a lot they do not understand about how startups and Silicon Valley work.
There was also reporting that Kyle was offered this role immediately after Dan was fired but turned it down, opting to remain interim CEO while they searched for a replacement. Looks like something has changed, or they couldn't find a suitable replacement.
That sounds like a [citation needed] to me. Surely there are UI problems to be solved in a car with a human being in the driver's seat, but the sensors and automation decisionmaking is going to be identical, and that's where the hard parts are.
Or alternatively: a less charitable way of making the point work would be to say that Cruise's stack was a bunch of special-case hacks for specific regions and vehicles and wasn't scalable to arbitrary environments nor regular passenger cars.
>The sensors and automation decisionmaking is going to be identical, and that's where the hard parts are.
Sensors will be very different. LIDAR prices are coming down but we’re still a while off from incorporating it into consumer vehicles - and we’re way, way off from incorporating multiple high resolution, long range LIDAR pucks, plus short range LIDAR to cover blind spots, plus imaging radar, plus thermal cameras, etc. into commercial cars the way they’re integrated into Cruise cars right now.
Automotive decision making will also be extremely different. Modern robotaxis rely on very high detail HD maps that are continuously updated. It’s impossible to scale that nationwide in a way that would work in a consumer car. Fundamental parts of the stack assume these maps are present and accurate - remove that assumption and a ton of things have to be rethought from first principles.
Remote support is also a key part of AV stacks - that is, asking a human to clarify an ambiguous situation. There’s a video where Kyle says that Cruise cars request remote support approximately every 5 minutes. Again, fundamental parts of the stack rely on the availability of remote support and have to be rethought from first principles if it’s removed.
This isn’t even getting into the differences in compute on a Crusie car and a consumer car.
>Or alternatively: a less charitable way of making the point work would be to say that Cruise's stack was a bunch of special-case hacks for specific regions and vehicles and wasn't scalable to arbitrary environments nor regular passenger cars.
I mean you’re not wrong, but you can’t create a robotaxi without this. ML models just aren’t capable enough to handle edge cases in a safe way without tons of hacks in place.
What are the challenges here? Is it simply the different scale required on the backend to handle tens (hundreds?) of millions of privately-owned cars, vs. that required for orders of magnitude fewer robotaxis? If so, I don't think that's all that insurmountable. I guess one thing that would worry me there would be bandwidth on that scale, as well as what happens when a privately-owned car is taken into an area where it doesn't have connectivity. I assume a robotaxi would just refuse to go where it can't talk to the internet, while that would be unacceptable for a private car to do. (Then again, the private car could still have manual drive controls, and require a driver to take over when internet connectivity is lost.)
I'd be hesitant to generalize this lesson. Another case of "adult supervision", in that case against the wishes of the founders, was.... Eric Schmidt at Google. Say what you want about Google, but it's difficult to say that they weren't successful under his tenure (2001-2011)
Dan Ammann took over and made really substantial progress. Ammann is widely considered to be the reason Cruise is where it is today. His record of success was in sharp contrast to Vogt's consistent record of failure.
Unfortunately, Ammann disagreed with GM's CEO about Cruise's future as a business. Employees at my level of seniority don't know the details, but many of us are skeptical that Kyle is the right man for the job.
And while Ammann continued to push the company to expand, there were missed targets, notably the plan to launch a commercial robotaxi business in 2019. The company has spent the past two years inching toward that commercialization goal, along with the rest of the industry, which has gone through a spate of consolidation.
Most likely that's a lot harder to get done than anyone thinks. Is Vogt really the guy to make it happen? I guess we'll find out. But GM sending an otherwise successful VP packing after more than a decade there signals they are looking to shake things up. GM is not Silicon Valley and even senior execs IMHO enjoy longer tenures that you'd find in the Valley. They also skipped over the whole reassigning him to another role / oh he's left to pursue other interests tap dancing you often see to give people some runway or cover to leave. Not sure whether to read anything into that or if that's just how Barra operates.
[1] https://techcrunch.com/2021/12/16/longtime-gm-exec-dan-amman...
Ammann inherited Vogt's mess, and at that time nobody in management fully understood how bad the situation was. Ammann promptly began fixing things and we see the fruits of that today.
Ammann's departure, to the best of our knowledge, is a result of a conflict with GM's CEO regarding the future of Cruise as a business.
Hopefully Vogt can preserve, and successfully build on, what Ammann accomplished.
Is MS the bare minimum required?
Ironically I ended up canceling in large part because of the CEO spat.. it gave me some uncertainty about if they were committed to L5. Especially vs serving as GM's L3 supplier while paying L5 lip service indefinitely (and never going public)
Personally, the idea of "a wire in the road" by which I mean something like cats-eyes in the road but with RFID tags placed every 40 feet, or some other common means maintained by the DOT that all cars can use to sense where they are, is neglected because every player in autonomous cars wants the "winner take all" method of being first, which will give them at least, a $25 billion market cap.
Uber alone has a market cap nearly 3x that and they have explicitly said they will only become profitable as an autonomous taxi co. Tesla is worth nearly a Trillion on its own. Where do you get 25B from?
You can safely assume most of the major players have thought through ideas like this and abandoned them for good reasons. In this case, you wouldn’t be able to rely on these external sensors being online with 100% uptime, so you’d necessarily be forced to build the capabilities to operate without them anyways. And adding external sensors and local communications and trying to deal with different standards and models and interop adds a ton of complexity.

Well, yeah nobody said it was easy. But, it does seem like something that could work, whereas we know that fully autonomous is just not possible with the tech we have today.
Another thing to understand is that perception in the way you’re imagining these cameras would work isn’t really an issue for AVs right now. I don’t think the problem you’re describing is a real blocker for AVs.
Collabing with DoT is a terrible idea imo.
Anyone who has seen anything any DoT in America has tried to do in the last few decades should immediately know why. It will cost an astronomical amount of money along with an equal time length.
To put "wires in road", it would likely be a project on the scale of trillions and 50+ year deadline. It won't happen, it's more feasible to solve the problem of how to have smart cars on dumb roads rather than relying on bloated and corrupt DoT & contractors to do the work of making smart roads.
This isn't even to mention the likely quagmire of what happened with early railroads where the rails laid by different companies weren't compatible with each other and you had to switch to an entirely different train to continue your journey.
I'd LOVE to hear the reasons why this system won't work. If it is something other than all the big car companies refuse play nice with each other I will be SHOCKED.
You shouldn’t IMO scope the problem only to lane-keeping. That’s a very small part of the problem space. Solutions aimed at only that problem still leave the most important problems untouched.
Corner identifying, light changing, cross-walk identifying, speed limits, addresses. Not to mention, if the car can't mistake a hunched over person on the side of the road as a curb (because the curb identifies itself) it makes everything else easier to identify. More computation can be freed up to identify things that ARE NOT KNOWN if there is something that IS known.
The edge cases are the hard part. A human knows what to do when a random construction worker or cop is directing traffic. Self driving car? Not so much.

The HN ranking algorithm seems to put a lot of weight into both velocity and flags.
A few factors that may have caught people's attention to upvote: it's about an HN company, the author is an HN regular, everything you need to know is in the title, it's written in first-person, and it's a bit unusual for someone to return as CEO.
They all rejected the job when it was first offered to them. It should be a case study and research topic. I think the takeaway here is - don't accept the CEO job right away; conditionally, you should be inside the company. At least that was the case with the above individuals.
The good thing is we have comma.ai that works across a wide variety of vehicles.
I’m talking about Tesla. Imagine if the Boeing CEO one day woke up and started dictating the sensor modality of aircraft to his engineers? People would think it was crazy. Because, it is.
Critically, LIDAR still has to be trained in the same way cameras have to - it'll give you depth information, but you still have to make it accurate decide whether some 3D blob is a person, sign, etc. LIDAR does not help you recognize street markings, interpret signs etc.
That is the big question is: what is cheaper/faster: cheap sensors and more training, or more expensive sensors and less training. As LIDAR and training both get cheaper, it might not end up making much of a difference in the end. Companies will be successful based on how well they execute on the full stack and a slight edge in one area might not be enough to overcome problems elsewhere.
You’re right, but that “small part” is absolutely critical to get right. It’s what allows the rest of the stack to be built; without that cornerstone, there’s no product.
There had been many attempts at touch controls for computers before the iPhone. Other smartphones were trying. None of them were remotely close to what Apple achieved with their first capacitive screen, and that began a massive change in the way people interacted with their device, and changed the world.
It’s like saying your roof is only “a small part of” your house. You’re right, on some level, but without that roof, there’s not much point in a really nice kitchen.

Was cool.
They have had several tenders for the data required to build out the Super-Cruise maps but these have all been a disaster as clear the critical knowledge is gone.
Cruise AVs are much different. They appear to use LIDAR, radar, and camera data to understand their surroundings including intersections, pedestrians, and road hazards.
So who is the CEO of super cruise and isn't "super cruise" better than "cruise"? I see "ultra cruise" (with LIDAR) is coming soon. Geeeesh.
