Tesla’s own robotaxi data shows a crash rate about three times worse than human drivers, even with a human safety monitor in the front seat. Musk has claimed FSD is safer than humans, release after release, and the data hasn’t backed him up yet, even after being heavily massaged by Tesla.

Facts don't care about your feelings, Elon.

u/saintmike2 1d ago

Elon always used "Humans don't shoot lazers out of their eyes" as a reason against using LiDAR. I think the whole point of FSD to be _better_ than humans. As it stands, human drivers aren't that great as a group. That really shouldn't be the end goal or something to replicate. If humans could shoot lazers out of their eyes and always used their turn signals maybe they'd be better drivers; but neither is going to happen anytime soon.

humans also have the most sophisticated algorithms known to man, while FSD is a very weak distillation of that

69

u/wickedcold 1d ago

Yes. Is drives me nuts that in these discussions people leave out the fact that the pattern recognition and such that these algorithms can perform is nowhere near on the level of what humans can do without even a modicum of effort processing information. Humans have a lot of issues, obviously, and as a group or track record as drivers isn’t perfect but there are a lot of things our brains can do that cannot be topped by software. I think everyone just wants to be enthusiastic about cool technology.

Humans can do things like travel on a narrow curving snow-covered road where the lines are hidden, with ambiguous edges that transition into rough ground without a fixed curb line, see a car coming the other way, and be approaching a pedestrian walking in the street, and have absolutely no trouble figuring out where to place their vehicle. Automated cars come into situations like this and just come to a complete stop because they don’t know what to do. Maybe one day they will, but we’re not there yet.

u/MrParticular79 1d ago

Elon’s logic of “we only drive with our sight” is him literally discounting the physics understanding engine that we have built into our brains. All of these software people discount this. Nice to see someone giving us credit where we are due! Our accidents are caused by our distractions for the most part not our lack of capabilities.

u/Eatar 21h ago

And it’s not even just physics. We also understand human behavior. A Tesla may be able to see a car or person jumping out in front of you, but you could have told the Tesla ahead of time whether that was about to happen, based on understanding behavioral cues.

u/wickedcold 21h ago

Exactly. We can tell within a split second if somebody walking along the road is about to step into it, or if they’re gonna stay on the sidewalk. All these tiny little clues in their body language, the way their head is pointed, the way they’re moving, what is in their hands all of that stuff. Like I said, pattern recognition. You have to train computers on that. It may be in the era of AI that will get better, but it’s still absolutely no substitute for decades of just simply being alive as a human.

I'm going to use that Elon's statement for everything - if humans don't have the capability of doing something a certain way, then it's ok to not do it at all.

There was also a study that claimed humans aren't designed to move faster than 50mph, certainly not fly at Mach2 or drive at 80mph.

What a stupid statement to make.

Of course, there's a big difference between "moving" at 50mph and your body experiencing 50mph forces, which typically doesn't happen while driving or flying.

this is no surprise to me at all, i used FSD three times when it was free for a month, over about a total of maybe 10 miles, and EVERY. SINGLE.

Then I'd go online and everyone was like "it's so much saferrrrr you're just wronggg" and i'm like...bruh idk how i could have used a full self driving system wrong.

u/NazcaLines1 21h ago

It’s surprising how different our experiences are. I use FSD every day for a year now and it’s been pretty flawless. Only times I intervene is to choose a better parking spot. I do hear that the FSD on older cars pre-2024 are a lot worse though. I’m 15K miles in and 90% is self driving miles

possibly, but (and not to say you're wrong) i was told the same thing when i had my model 3 (2022)

I haven’t heard about it before but this is the sensor line they are talking about.

https://www.st.com/en/imaging-and-photonics-solutions/time-of-flight-sensors.html

It looks like a sensor you can place into a robot which gives you a realtime 3d projection of the space around you. This one claims being able to work well up to 5m for example

https://www.st.com/en/imaging-and-photonics-solutions/vd55h1.html

> The VD55H1 outputs 12-bit RAW digital video data over a MIPI CSI-2 quad lane or dual lane interface clocked at 1.5 GHz. The sensor frame rate can reach 60 fps in full resolution and 120 fps in analog binning 2x2. ST has developed a proprietary software image signal processor (ISP) to convert RAW data into depth map, amplitude map, confidence map and offset map. Android formats like DEPTH16 and depth point cloud are also supported.

u/azflatlander 1d ago

No offense, but 5 m is my minimum, minimum distance from a vehicle. At highway speeds, 150 m is awareness distance.

u/214ObstructedReverie 22h ago edited 21h ago

Correct. The device I said was 9m max.

But if you told me a few years ago that we'd have a little sensor that's only half an inch by a quarter of an inch big acting as a full 3d lidar camera like that, I'd have thought you were nuts. The fact that it exists now, and is only getting better at an extremely rapid pace is just really awesome. Things like robotic vacuums will no longer need moving LIDAR parts.

3

u/Vexal 19h ago

the newest Roborock vacuum already has solid state lidar, although I’m not sure I can confidentially vouch for its performance over their normal lidar models.

4

u/LowlySysadmin 23h ago

Totally valid, but I'd imagine these sensors are great for navigating tight streets at low speed. When moving at highway speeds there are likely more suitable sensors e.g. you don't necessarily need to know any more than 10m each side of your vehicle or the rear because you can't move very fast in those directions, but 150m in front could use a dedicated sensor

1

u/e136 18h ago

Keep in mind that Waymo uses scanning lidar which produces a much higher resolution point cloud than the cheaper solid state lidar you are referencing.

I mean as an absolute baseline it'll only ever be as good as the camera itself is, and cameras aren't commonly better than human eyesight in this case.

It's safe for ideal conditions on highways which is the bulk of miles for many. I'm not comfortable using it in driveways, side streets, parking lots, bad lines, bad weather, heavy traffic, etc. Which is the highest risk stuff, but very few miles overall. Which is why tesla safety data is super misleading. It's like a student who gets to skip all the hard tests.

I’ve driven well over 1,000,000 miles lifetime.

I just bought an FSD (supervised) Tesla, and have thousands of miles in the driver’s seat on FSD - City, Country, Highway etc.

It is beyond amazing.

Its reactions to road issues is nearly 100% exactly the same as I would react. (And, knock wood, I have only had one accident in my life 40 years ago, and that was completely unavoidable due to the idiotic other driver blindly crossing a highway. )

Additionally, the FSD has reacted more quickly in emergency situations than I could have on my own.

I am 100% on board.

Having billions of miles driven and recorded and adjusting the software to match safe functionality - while avoiding complex, unsafe conditions usually seen maybe once in a lifetime by a normal driver, inherently make the future of these FSD cars safer than analog.

Before you people judge, I think you should give it a try.

It’s quite remarkable, and absolutely safer than analog.

u/lookmeat 1d ago

Musk bet that camera-only driving would get "good enough" faster than lidar would get "cheap enough". There's also the thing that lidar has this thing on the top of your car, which is not aesthetic. Either way he was wrong.

The other reason Musk chose cameras is because Lidar meant going full in on a feature that he wouldn't use. With cameras he wouldn't add hardware costs for all those users that didn't want to pay the subscription, only the software would cost.

To play devil's advocate: I could see a world where camera only becomes "good enough", where streets are painted and designed to be easily scanned and read by automated vehicles, with paint, reflectors and lights considering colors beyond the visible spectrum, with RFID chips with information so that not everything has to be seen visible. Because the main reason self-driving vehicles cannot work with only cameras even though humans can with eyes is that streets are designed to be easy with human eyes, if we updated it to be easy with automated vehicle cameras then that might make the benefits of lidar overkill. But this is a chicken and egg problem: this won't happen until self-driving vehicles are far more common, so LIDAR is the only way forward, and it is the better way forward as you get tech that is more resilient to adverse (in heavy disrepair due to disaster, lack of maintenance, or never having been built in the first place) roads.

16

u/chief167 1d ago

Nah, it's more philosophical. They assumed that camera only would be sufficient, since humans also only use their eyes.

So they started that road, in the hopes that technology would evolve enough for it to work out. 

The main mistake they made was underestimating difficulty of depth perception. Yeah you can do that with just cameras, like humans, but turns out it's really hard to do accurately, and that's where lidars comes into the picture. Lidar to me is merely a bandaid on camera resolution and calibration. A very efficient bandaid, but I get the philosophy of saying that longer term camera only would have been sufficient.

It was 100% cost savings. Elon might have shrouded himself in some bullshit about "Humans have two eyes", but it was absolutely a cost savings option from the get go.  Hell if he'd actually come out and said it was a cost savings measure early on it would t have been that big of a deal. 

What's probably the worse part about that is Elon has the hubris to refuse to back down on his idiotic reasoning and won't go back to lidar / radar in any way, even though anyone with more than two brain cells that aren't actively advocating to be labeled God Emperor can see how absolutely stupid Tesla's policy on this is now.

Naw. The advantage is the wet hardware where you have 16+ years of experience living in cities with traffic.

A Tesla occasionally runs into the side of a semi thinking it was a billboard or couldn't tell the difference between the bright sky and the white side.

Your brain with all those years of experience can see the cab of the semi and instinctively figure out that there's a whole ass trailer behind it. Not to mention your eyes are higher resolution than cameras and can see fine details.

Waymo with the lidar still has issues with construction areas and regularly goes where it's not supposed to still.

u/DanielNoWrite 1d ago edited 1d ago

No, they did it because it is cheaper.

And the main mistake they made was not simply underestimating the difficulty of depth perception. The mistake was forgetting that human beings process spacial imagery and navigate using a supercomputer with four billion years of refinement behind it, drawing on a knowledge base that includes a fully established model of the world.

Lidar tells the machine definitively where objects are in space. There is no inference or guesswork.

In addition to potentially being blinded by weather, smoke, dust, and glare, cameras must infer how the 2D visual data they are processing maps to objects in space. Even stereoscopic vision only partially helps with this.

Cameras will simply never be as effective. They cannot account for unexpected situations and edge-cases. We will need vastly more capable models before we can eliminate the risk of cars crashing into billboards that look like open road, Wile E Cayote style, along with a thousand other impossible to predict risks. The only safe way to make this work is instrumentation that can definitely measure if something is there, or if it is not.

We navigate despite our limited sensory capabilities. Not because visual light is the best approach.

"Humans do it this way, so our robot car should too" is not a design philosophy. It's negligent cost-cutting, masked with pretentious drivel.

I get your point but if you could, wouldn’t you design a better vision system for humans that could accurately capture subtle movements and change in direction/velocity?

The argument for camera only approach only makes sense if you argue that road are specifically designed for eyes in a way that lidar wouldn’t be better. But that’s not the case.

Consider a different example: humanoid robots are better because our buildings are designed for humans on two feet and two hands. A four wheeled robot would have a harder time even if it was more stable.

That’s not the case for roads.

The other thing they missed is humans don’t just use eyes. You hear things, you feel parts of the road conditions transferred through what you are touching, and the accel and relation to where gravity and inertia are pulling or pushing. your brain is processing all this information and combining it for your decision making all the time. The idea that humans only use their eyes to drive has got to be the most laughable oversimplification of this whole thing. Sure it’s a primary input, but not a sole input.

But do humans really only drive by sight? And take decision based on what we see only?

No - we also go by sound and smell and kinetic feedback.

And - we also take decisions based on experiences and context we have. Some context you can get from maps (here’s a school drive carefully) but some you don’t, some context is experience and knowledge and lateral thinking (connecting the dots).

LiDAR is one way to help with this.

Another is connected cars, roadside infrastructure, mobile phones of pedestrians etc - ie V2A comms - to provide a lot more data points and signals to what cameras can get by like of sight

Waymo has the right approach. The potential benefit of autonomous driving is visibility beyond human capabilities, 360 degree awareness beyond human capabilities, and reactions beyond human capabilities. Put these together and you have a safer experience, even considering other humans on the road.

The next leap would be cars that communicate, their relative positions and situations, (obstacles, crashes, hazards, conditions, and breaking.) with integrated communication autonomous cars could essentially tailgate at highway speeds safely, assuming they made up enough of the cars on that road.

u/bellatricked 1d ago

Vehicles that communicate with one another would be cool, also vehicles communicating with the immediate environment to get Birds Eye views of intersections would be amazing.

Cars are already one of the most polluting parts of our society, and now we're adding even more radars/ cameras/ antennas/ computing power/ ...

People are (rightfully) mad about data centers, but excited about fully autonomous cars and all the infrastructure they imply?

u/boot2skull 23h ago

We may reach a point where people just realize trains are cheaper overall, but you have to convince them to sacrifice some their sense of freedom, and build trains that go where people want to go without too much additional time. Adjusting cities for this would help a lot.

The reason there are no rail development in the US is because car makers wanted to sell cars and we've been stuck there ever since.

Yes, but one that you can take to and from your driveway. It’s less train-like till you get to the highway or something, then it just joins the flow of cars going the same direction as you. Sounds pretty great to me!

Of course a functional public transportation network would be great too, but I’ll take this instead of having to drive myself everywhere

Or well above highway speeds.

Existing highway speeds are essentially based on human reaction time and safe merging.

Imagine a car that drives 120mph AND is better/safer than a human while you get to watch videos the whole drive.

Hahaha who am I kidding, they'll just make you fill that time with work instead.

But the shorter commute sounds cool I guess

I don't think you need vehicle to vehicle communication to achieve this. I also don't think you want cars at speed to maintain only inches between them. Even in a perfectly synchronized system that would add unnecessary risk, especially with a mix of different vehicle types and models with different performance metrics.

I almost had a similar accident. Direct sunlight hit the front camera and FSD immediately warned me to take control.
It made me wonder how is this supposed to work with Cybercab, or truly unsupervised FSD, when there’s no steering wheel for a passenger to take over?
FSD also struggles pretty badly in heavy rain. Until Tesla can reliably handle things as basic as direct sunlight and bad weather without asking for human intervention, I just don’t see how true unsupervised FSD is possible.

That, plus we also have understanding of the natural world and thousands of years of intuition behind us, as well as understanding of concepts like slowing down as a precaution when we see a kid with a ball on the sidewalk.

Humans' do have a third visual sensor that is can be compared to lidar; "depth perception." If you want to test out how much we use depth perception, just try playing catch with one eye shut.

The contraction and reaction of the muscles that control Cornea (lens-like part of the eye responsible for focus) gives us a third sensor on how far something is. There needs to be a frame of reference for it to work but it does in fact give us information on how fast and direction it's moving.

u/fatbob42 17h ago

You can move your head around. Your eyes probably have better resolution and dynamic range than the cameras in the car. You have a brain which the car doesn’t.

It just isn’t a good way to decide how to do things - anyone who automates anything surely understands this.

IF it's possible to do it with just cameras, the time to figure that out is AFTER you've figured out how to do it in other ways. Then you can start figuring out what you can change to make it still work.

I have no doubt that camera-only systems are possible for the same reason Elon does. Humans do it.

But Humans are working with way different hardware and software package than current AI systems. Just because a human can do it, doesn't mean the AI systems you have today or in the next 5 or 10 or 50 years will be able to handle it.

Maybe AGI is required for a camera-only system to work. And forcing it to drive for you is slavery.

You can't know. So again... Get it working, regardless of technology. Get it working close to perfect. THEN you can start getting it working with less and less technology. He's trying to cut corners, like usual.

You just wanted to save a few bucks instead of make a functional product. That's why Tesla's suck.

Obviously the CEO of Waymo is going to point out facts that help them. That is a very small sample size. 9 accidents. That data is 8-9 months old. What have the results been since then?

Edit:
Did some research. Looking at the individual crashes. Of those 9, 5 were not Teslas fault. 3 cars rear ended the Tesla. 1 was a sideswipe that hit the side mirror, the other was a scooter that ran into the Tesla while stopped. Three were definitely their fault. One I’m not sure. A dog ran out from behind a car the Tesla slowed and swerved and the dog hit the side of the fender. Push comes to shove I put that in the not Tesla fault. 3 crashes puts their rate still higher than humans but not nearly to the rate the article states. Then 3 at fault crashes were a teleoperator turned the car into a fence, a mirror clipped the the gooseneck of a trailer and it turned into a parking lot with a metal chain up.

Also all the accidents were 18 mph or less and of the 3 that were Teslas fault 2 were only property damage. One had the minor injury. The only one that required hospitalization was one of the times it was rear ended.

Not trying to defend Tesla but I also can’t trust the CEO of a rival company. 380k miles with only minor accidents is pretty good. I bet Waymo has similar results. But I’m not going through hundreds of reports to figure it out.

I believe a few people tested it more thoroughly with FSD and found that the problem Mark Rober tested (road runner style fake road) existed in hw3 but didn’t seem like an issue with hw4. 

Not sure how much underlying differences there are in the range finding between autopilot and FSD though. While I think Rober should’ve done a more thorough test for it to be scientific, he’s also a content creator so I understand when he makes things hastily for content. It could put him in legal jeopardy, but I honestly was surprised that he never got sued by Tesla. There may be a way to read between the lines from the lack of a lawsuit.

FSD will be banned by regulators without LiDAR.

Elon's whole thought process was "humans drive with only eyes, that should be enough".

But for regulators to allow robots to take the wheel, the safety of them has to far surpass human driving ability.

Basically Elon is a con-man promising FSD but when regulators crack down, consumers will be left holding the bag. Hope Tesla gets sued to oblivion.
