Obviously there is a huge amount of money and effort being spent on automated driving. But I cannot help thinking that this perception technology will prove very useful for robotics in general, factory, home, in space, etc. Car dynamics are fast enough to be useful across a huge number of domains.
In some sense, the visionaries in this space are not thinking big enough. I want visions of mobility with a totally different size, look, speed, etc. autonomous Golf carts? tuktuks? A moving autonomous bicycle carrier? etc
Like imagine a low speed, electric, autonomous, golf-cart-only lane at every train station, for the last mile.
The lead that Waymo has acquired in perceiving its driverless car's environment will be almost impossible to kill. In about 5 years, it'll be like NVidia and CUDA. Tesla's choice to abandon lidar will be one of the biggest oof in business history.
If you look at it from an outside point of view, right now Tesla is worth $1.6T, Waymo is worth $130B, and GM is worth $72B. If Cruise were actually a third viable competitor in this race, it would probably be worth more than the rest of GM. Self-driving is just a far more valuable business than car-making.
So from that point of view it would make sense to say, don't worry about the rest of GM too much, you should be willing to sacrifice all of that to increase the changes of making Cruise work.
It's hard to change the culture at a place like GM though. Does the GM CEO really want to take a huge amount of risk? Would they be willing to take a 50-50 shot where they either 10x the company's value or lose it all? Or would they prefer to pay a few billion dollars to avoid that risk.
We should not forget this is the same company that had an amazing lead on everyone in the electric car market 3 decades ago with the EV1. See "Who Killed the Electric Car [0]
Pushing Dan Ammann out was a bad idea. I personally like the original set up at the time. Kyle as the CTO and Dan as the CEO. Kyle was great as an internal CEO, he was calling most of the internal shots anyway. The accident would have played out very differently if Dan Ammann was the CEO IMO.
Was always unclear to me whether DanA was truly pushed out, or if the board (largely comprised of GM execs) wanted to take the company in a different direction than Dan wanted to go, and Dan decided to leave rather than stick around. Ie. IPO vs keep it a majority owned subsidiary.
I got the impression that it was a conflict with Mary Barra specifically, not so much the board as a whole. They simply went along with her. The tone of the notice was indicative of being pushed out, not a mutual parting of ways.
As an outsider I assumed it took GM a substantial investment just to realize how far out of their depth they were. It made sense to cut their losses once they figured this out.
Having experience and capability to manufacturer cars has approximately zero benefit to create a self-driving software/sensor stack. It would make more sense for Adobe to create a self-driving car than GM.
Cruise was being operated as a separate company though. As a default, GM could have just not done anything and let Cruise operate as if it were independent. Any synergies (personnel, manufacturing expertise, etc) would have just been a bonus. And if they didn't want the financial exposure, they could have spun it out again.
Instead they chopped it up for spare parts, specifically, sending some Cruise personnel to work on deadend GM driver assistance tech and firing the rest. Baffling.
I remember GM cars in Herzliya, Israel with cables and cameras held by duct tape circa 2019 after Andrej Karpathy already presented end to end neural network training for Autopilot in Tesla. Looked like very late to the party.
I liked my one and ride in Cruise however the problem I had was it took 10 minutes or so for my car to depart.
Car arrives. I get in. The car is sitting there getting ready to depart but not moving. After a few minutes I hit the button to call support. Someone tells me it's about ready to go. Ten minutes later it starts leaving.
I have no idea why it took so long to start but it wasn't a great experience.
If you (or anyone else from Cruise) can explain what was going on, that would settle the difference in experience to me.
This is a business with winner-take-all characteristics. Cruise was unlikely to leapfrog Waymo. So it makes the case for continuing to throw money at this very unconvincing.
Cruise was always destined to be "like Waymo, but worse". Tesla, on the other hand, is taking a very different path than Waymo, they have a chance at beating Waymo at their own game and even if they don't beat Waymo, they can be a winner in some specific niche. (For the record, I'm a fan of Waymo.)
What, why? There's no winner-take-all aspect to shuttling people around. Taxi service is a commodity and taxis-without-drivers will also be a commodity. The switching costs for users are essentially zero.
That's how we get Uber, Lyft, DiDi, Grab, Bolt, WeRide, BlackWolf...
I don't know how you can write that list and come to the conclusion that it's not winner-take-all. In their home market (US), Uber is ~75%, Lyft is ~25%, and all other competitors are sub-1% combined. Didi is similarly dominant in China, and so on. "Completely different markets have different winners taking it all" does not counteract the claim of winner-takes-all in any way, nor does listing utterly insignificant players like BlackWolf.
Maybe I'm giving GM too much credit, but it seems to me that GM acquired the technology with the intention to bring it into their vehicles as driver assistance, not autonomous driving. They were pretty candid about not wanting to operate taxis. Cruise itself was embroiled in investigations and was prohibited from operating in SF and voluntarily ceased operations in other markets, which basically made it a target, and since GM had already dumped a few billion into it, it probably made sense to at least get unencumbered rights to the tech.
Cruise was actually just about to return to market after the October incident [1]. We had reached efficacy on all (much harder) internal safety benchmarks showing the car had significantly improved.
GM pulled the rug on us a day or two before announcing. The current Cruise CEO wasn't aware at all either. I have my own conspiracies of why GM did this, but GM also has a long history of fumbling the ball.
It seems the time car companies thought more than 4 years ahead was in 2007 and that culture was swiftly removed from the industry out of the economic shock that occurred shortly after.
The ambiguity in the title is going to get a lot of the "skeptics" who have remained in denial about this to assume it's some kind of admission that they haven't been autonomous this whole time.
It's weird how many people there are like that still.
But what they mean is that they are putting the new release into production (without backup drivers). They have been fully autonomous for many years.
Is this one going to stop parking on the side of city streets with the hazards on the middle of rush hour?
For all the impressive technological advances Waymo makes (and don’t get me wrong, they are impressive), their cars are still a constant obnoxious menace to drivers.
> Our experience as the only company operating a fully autonomous service at this scale has reinforced a fundamental truth: demonstrably safe AI requires equally resilient inputs. This deep understanding of real-world requirements is why the Waymo Driver utilizes a custom, multi-modal sensing suite where high-resolution cameras, advanced imaging radar, and lidar work as a unified system. Using these diverse inputs, the Waymo Driver can confidently navigate the "long tail" of one-in-a-million events we regularly encounter when driving millions of miles a week, leaving nothing to the imagination of a single lens.
According to Elon, "sensor ambiguity" is a danger to the process [1], and therefore only a single type of sensor is allowed. (Conveniently ignores that there can be ambiguity/disagreement between two instances of the same type of sensor)
The fact that people still trust him on literally anything boggles my mind.
Sensor fusion allows you to resolve that ambiguity, I wonder if Elon is really as in touch with this as you would expect. No single sensor is perfect, they all have their problematic areas and a good sensor fusion scheme allows you to have your sensors reinforce each other in such a way that each operates as close as possible to their area of strength.
No single sensor can ever give you that kind of resilience. Sure, it is easy in that you never have ambiguity, but that means that when you're wrong there is also nothing to catch you to indicate something might be up.
This goes for any system where you have such a limited set of inputs that you never reach quorum the basic idea is to have enough sensors that you always have quorum, and to treat the absence of quorum as a very high priority failure.
Sensor ambiguity is straight up useful as it can allow you to extract signals that neither sensor can fully capture. This is like... basic stuff too, absolutely wild how he's the richest person in the world and considered this absolute genius
I bought mine with cameras and a radar, which they then deprecated and left an unused. Even though autopilot was better when it had radar. Then I realized that this thing would never be self-driving and that its CEO was throwing nazi salutes. Cut my losses and got rid of it. Gotta admit defeat sometimes.
Do Tesla fans think that? I've seen plenty of Tesla fans say that lidar is unnecessary (which I tend to agree with), but never that lidar is actively detrimental as Musk says there.
I mean, humans have only their eyes. And most of them intentionally distract themselves while driving by listening to music, podcasts, playing with their phones, or eating.
I get your point about camera vs lidar. Humans do have other senses in play while driving though. We have touch/vibration (feeling the road surface texture), hearing, proprioception / acceleration sense, etc. These are all involved for me when I drive a car.
Personally as much as people like to dunk on Musk, he did build several successful companies in extremely challenging domains, and he probably listens to the world-leading domain experts in his employ.
So while he might turn out to be wrong, I don't think his opininon is uninformed.
I fully agree with your first point: Musk has shown tremendous ability to manage companies to become unicorns. He's clearly skilled in this domain.
However, if you think about this for 2 seconds with even a rudimentary understanding of sensor fusion, more hardware is always better (ofc with diminishing marginal value).
But ~10y ago, when Tesla was in a financial pinch, Musk decided to scrap as much hardware as possible to save on operational cost and complexity. The argument about "humans can drive with vision only, so self-driving should be able to as well" served as the excuse to shareholders.
And to some extent, I also drive with my ears, not only with 2 eyes. I often can ear a car driving on the blind spot. Not saying that I do need to ear in order to drive, but the extra sensor is welcome when it can helps.
There is an argument for sure, about how many sensors is enough / too much. And maybe 8 cameras around the car is enough to surpass human driving ability.
I guess it depends on how far/secure we want the self-driving to be. If only we had a comprehensive driving test that all (humans and robots) could take and be ranked... each country lawmakers could set the bar based on the test.
Nuanced point: Even if vision alone were sufficient to drive, adding sensors to the cars today could speed up development. Tesla‘s world model could be improved, speeding up development of the vision only model that is truly autonomous.
The other day I slammed the brakes at a green light, because I could hear sirens approaching -- even though the buildings on the corner prevented any view of the approaching fire trucks or their flashing lights. Do Teslas not have this ability?
Stongly disagree. I don‘t like the fella but thinking that he founds and successfully manages SpaceX and Tesla to their market value _by chance_ is ridiculous.
What doesn’t make sense to me is that the cameras are no where as good as human eyes. The dynamic range sucks, it doesn’t put down a visor or where sunglasses to deal with beaming light, resolution is much worse, etc. why not invest in the cameras themselves if this is your claim?
I always see this argument but from experience I don't buy it. FSD and its cameras work fine driving with the sun directly in front of the car. When driving manually I need the visor so far down I can only see the bottom of the car in front of me.
The cameras on Teslas only really lose visibility when dirty. Especially in winter when there's salt everywhere. Only the very latest models (2025+?) have decent self-cleaning for the cameras that get very dirty.
> I fully agree with your first point: Musk has shown tremendous ability to manage companies to become unicorns. He's clearly skilled in this domain.
I would firmly disagree with that.
What Musk has done is bring money to develop technologies that were generally considered possible, but were being ignored by industry incumbents because they were long-term development projects that would not be profitable for years. When he brings money to good engineers and lets them do their thing, pretty good things happen. The Tesla Roadster, Model S, Falcon 9, Starlink, etc.
The problem with him is he's convinced that he is also a good engineer, and not only that but he's better than anyone that works for him, and that has definitively been proven wrong. The more he takes charge, the worse it gets. The Model X's stupid doors, all the factory insanity, the outdoor paint tent, etc. Model 3 and Model Y arguably succeeded in spite of his interference, but the Dumpstertruck was his baby and we can all see how that has basically only sold to people who want to associate themselves closely with his politics because it's objectively bad at everything else. The constant claims that Tesla cars will drive themselves, the absolute bullshit that is calling it "Full Self Driving", the hilarious claims of humanoid robots being useful, etc. How are those solar roofs coming? Have you heard of anyone installing a Powerwall recently? Heard anything about Roadster 2.0 since he went off claiming it would be able to fly? A bunch of Canadian truckers have built their own hybrid logging trucks from scratch in the time since Tesla started taking money for their semis and we still haven't seen the Tesla trucks haul more than a bunch of bags of chips.
The more Musk is personally involved with a project the worse it is. The man is useful for two things: Providing capital and blatantly lying to hype investors.
If he had stuck to the first one the world as a whole would be a better place, Tesla would probably be in a much better position right now.
SpaceX was for a long time considered to be further from his influence with Shotwell running the company well and Musk acting more as a spokesperson. Starship is sort of his Model X moment and the plans to merge in the AI business will IMO be the Cybertruck.
You say that you disagree with my point, but then your first paragraph just restates my argument. And your subsequent paragraphs don‘t refer to my comment at all.
I never claimed he‘s a good engineer, nor that he has high EQ, nor that he is honest, nor that he has sole responsibility for the success of his companies.
I don't thing it's purely stubbornness. Tesla sold the promise of software only updates resulting in FSD to hundreds of thousands of people. Not all of those people are in the cult of Tesla. I would expect admitting defeat at this point would result in a large class action lawsuit at the very least.
I know it's "illegal" and technically sold as FSD (assisted), but just 2 days ago I was in a friend's Model Y and it drove from work to my house (both in San Jose) without any steering wheel or pedal touch, at all. And he told me he went to Palm Springs like that too.
I shit on Tesla and Elon on any opportunity, and it's a shame they basically have the software out there doing things when it probably shouldn't, but I don't think they're that far behind Waymo where it really matters, which is the thing actually working.
It wouldn't keep them from equipping _new_ models with additional sensors, spinning a story around how this helps them train the camera-only AI, or whatever.
Elon cult members still to this day will tell me that because humans only use vision to drive all a Tesla needs is simple cameras. Meanwhile, I've been driven by Waymo and Tesla FSD and Waymo is by far my pick for safety and comfort. I actually trusted the waymo I was in, while the Tesla I rode in we had 2 _very_ scary incidents at high speeds in a 1 hour drive.
I love this argument because it is so obviously wrong: how could any self aware person seriously argue that hearing, touch, and the inner ear aren't involved in their driving?
As an adult I can actually afford a reliable car, so I will concede that smell is less relevant than it used to be, at least for me personally :)
Human inner ear is worse than a $3 IMU in your average smartphone in literally every way. And that IMU also has a magnetometer in it.
Beating human sensors wasn't hard for over a decade now. The problem is that sensors are worthless. Self-driving lives and dies by AI - all the sensors need to be is "good enough".
Human hearing is excellent. Good directional perception and sensitivity.
Eyesight is the weakest sense. Poor color sensitivity, low light sensitivity, blindspot. The terrible natural design flaws are compensated by natural nystagmas and the brain filling in the blanks.
Well, in TFA the far more successful manufacturer of self driving cars is saying you're wrong. I think they're in much better position to know than you :)
(1) is true, but actually driving is definitely harder without hearing or with diminished hearing. And Several US states, including CA, prohibit inhibiting hearing while driving, e.g., by wearing a headset, earbuds, or earplugs.
I've long expected Waymo's approach to prevail simply because - aside from whether vision-only proves good enough to some standard - it will be easy to lobby for regulations that favor the more conservative approach.
But I also don't think we can take anything from what Waymo claims about the feasibility of vision-only.
I think past experience shows that the US prefers a wait and see approach - owning in part I think to it federal structure, where states compete for companies good graces and money, so if State A bans something, State B will allow it and gain an advantage in that area.
Moreover, why draw a hard line on vision only when there is existing technology is available to augment it? It's not like they have to develop 3 novel technologies.
Obviously there is a huge amount of money and effort being spent on automated driving. But I cannot help thinking that this perception technology will prove very useful for robotics in general, factory, home, in space, etc. Car dynamics are fast enough to be useful across a huge number of domains.
In some sense, the visionaries in this space are not thinking big enough. I want visions of mobility with a totally different size, look, speed, etc. autonomous Golf carts? tuktuks? A moving autonomous bicycle carrier? etc
Like imagine a low speed, electric, autonomous, golf-cart-only lane at every train station, for the last mile.
The lead that Waymo has acquired in perceiving its driverless car's environment will be almost impossible to kill. In about 5 years, it'll be like NVidia and CUDA. Tesla's choice to abandon lidar will be one of the biggest oof in business history.
I'm forever baffled that GM gave up on Cruise just as soon as Waymo was proving that autonomous driving is feasible.
(Disclaimer: former Cruise employee)
It seems tough culturally.
If you look at it from an outside point of view, right now Tesla is worth $1.6T, Waymo is worth $130B, and GM is worth $72B. If Cruise were actually a third viable competitor in this race, it would probably be worth more than the rest of GM. Self-driving is just a far more valuable business than car-making.
So from that point of view it would make sense to say, don't worry about the rest of GM too much, you should be willing to sacrifice all of that to increase the changes of making Cruise work.

What path is that? Their self driving took a huge step back when they dropped Mobileye and honestly I don't think it's been the same since.

Truly. I don't understand why Tesla fans think camera/lidar fusion is unsolvable but camera/camera fusion is a non-issue.
Because they bought a Tesla with only cameras on it.
Admitting this would be admitting their Tesla will never be self driving.
I bought mine with cameras and a radar, which they then deprecated and left an unused. Even though autopilot was better when it had radar. Then I realized that this thing would never be self-driving and that its CEO was throwing nazi salutes. Cut my losses and got rid of it. Gotta admit defeat sometimes.
Add a tow hitch to Waymos and any car can be autonomous!

Especially the part where the cameras do not meet minimum vision requirements [1] in many states where it operates such as California and Texas.

The constant claims that Tesla cars will drive themselves, the absolute bullshit that is calling it "Full Self Driving", the hilarious claims of humanoid robots being useful, etc. How are those solar roofs coming? Have you heard of anyone installing a Powerwall recently? Heard anything about Roadster 2.0 since he went off claiming it would be able to fly? A bunch of Canadian truckers have built their own hybrid logging trucks from scratch in the time since Tesla started taking money for their semis and we still haven't seen the Tesla trucks haul more than a bunch of bags of chips.
The more Musk is personally involved with a project the worse it is. The man is useful for two things: Providing capital and blatantly lying to hype investors.
If he had stuck to the first one the world as a whole would be a better place, Tesla would probably be in a much better position right now.
SpaceX was for a long time considered to be further from his influence with Shotwell running the company well and Musk acting more as a spokesperson. Starship is sort of his Model X moment and the plans to merge in the AI business will IMO be the Cybertruck.
You say that you disagree with my point, but then your first paragraph just restates my argument. And your subsequent paragraphs don‘t refer to my comment at all.
I never claimed he‘s a good engineer, nor that he has high EQ, nor that he is honest, nor that he has sole responsibility for the success of his companies.
His autopilot has killed several people, sometimes the owner of the car, sometimes other drivers sharing the road. It is hard to root for this guy.
I certainly don't trust anything he says 100%.
This is - to me - entirely separate from the fact that his companies routinely revolutionize industries.
If only there was a filter so we could fuse different sensor measurements into a better whole..
I don't thing it's purely stubbornness. Tesla sold the promise of software only updates resulting in FSD to hundreds of thousands of people. Not all of those people are in the cult of Tesla. I would expect admitting defeat at this point would result in a large class action lawsuit at the very least.
I know it's "illegal" and technically sold as FSD (assisted), but just 2 days ago I was in a friend's Model Y and it drove from work to my house (both in San Jose) without any steering wheel or pedal touch, at all. And he told me he went to Palm Springs like that too.
I shit on Tesla and Elon on any opportunity, and it's a shame they basically have the software out there doing things when it probably shouldn't, but I don't think they're that far behind Waymo where it really matters, which is the thing actually working.
It wouldn't keep them from equipping _new_ models with additional sensors, spinning a story around how this helps them train the camera-only AI, or whatever.
The terms of service probably require you to sue Tesla in that Texas district with his corrupt judge pal.
Elon cult members still to this day will tell me that because humans only use vision to drive all a Tesla needs is simple cameras. Meanwhile, I've been driven by Waymo and Tesla FSD and Waymo is by far my pick for safety and comfort. I actually trusted the waymo I was in, while the Tesla I rode in we had 2 _very_ scary incidents at high speeds in a 1 hour drive.
> humans only use vision to drive
I love this argument because it is so obviously wrong: how could any self aware person seriously argue that hearing, touch, and the inner ear aren't involved in their driving?
As an adult I can actually afford a reliable car, so I will concede that smell is less relevant than it used to be, at least for me personally :)
> hearing, touch, and the inner ear aren't involved
Not to mention possibly the most complex structure in the known universe, the human brain: 86 billion neurons, 100 trillion connections.
Human inner ear is worse than a $3 IMU in your average smartphone in literally every way. And that IMU also has a magnetometer in it.
Beating human sensors wasn't hard for over a decade now. The problem is that sensors are worthless. Self-driving lives and dies by AI - all the sensors need to be is "good enough".
Human hearing is excellent. Good directional perception and sensitivity. Eyesight is the weakest sense. Poor color sensitivity, low light sensitivity, blindspot. The terrible natural design flaws are compensated by natural nystagmas and the brain filling in the blanks.
> The problem is that sensors are worthless
Well, in TFA the far more successful manufacturer of self driving cars is saying you're wrong. I think they're in much better position to know than you :)
1. in US you can get a driver's license if you're deaf so as a society we think you can drive without hearing
2. since this is in context of Tesla: tesla cars do have microphones and FSD does use it for responding to sirens etc.
(1) is true, but actually driving is definitely harder without hearing or with diminished hearing. And Several US states, including CA, prohibit inhibiting hearing while driving, e.g., by wearing a headset, earbuds, or earplugs.
Involved? Yes. Necessary? Pretty sure no.
If it makes you happy, you can read "only vision" as "no lidar or radar." Cars already have microphones and IMUs.
I've long expected Waymo's approach to prevail simply because - aside from whether vision-only proves good enough to some standard - it will be easy to lobby for regulations that favor the more conservative approach.
But I also don't think we can take anything from what Waymo claims about the feasibility of vision-only.
Waymo has posted videos of accidents they've avoided purely because their lidar picked up on a pedestrian before their cameras saw anything.

They're very public about the data that makes them look good, but they went to court to keep their safety data from the public. (https://techcrunch.com/2022/02/22/waymo-to-keep-robotaxi-saf...)
I think past experience shows that the US prefers a wait and see approach - owning in part I think to it federal structure, where states compete for companies good graces and money, so if State A bans something, State B will allow it and gain an advantage in that area.
Moreover, why draw a hard line on vision only when there is existing technology is available to augment it? It's not like they have to develop 3 novel technologies.
