‘Lidar is lame’: why Elon Musk’s vision for a self-driving Tesla taxi faltered
Powderhornhttps://www.theguardian.com/technology/2025/jun/29/elon-musk-tesla-robotaxi
After years of promising investors that millions of Tesla robotaxis would soon fill the streets, Elon Musk debuted his driverless car service in a limited public rollout in Austin, Texas. It did not go smoothly.
The 22 June launch initially appeared successful enough, with a flood of videos from pro-Tesla social media influencers praising the service and sharing footage of their rides. Musk celebrated it as a triumph, and the following day, Tesla’s stock rose nearly 10%.
What quickly became apparent, however, was that the same influencer videos Musk promoted also depicted the self-driving cars appearing to break traffic laws or struggle to properly function. By Tuesday, the National Highway Traffic Safety Administration (NHTSA) had opened an investigation into the service and requested information from Tesla on the incidents.
Let me tell you how thrilled we all are to have a new hazard added to Austin streets.

Do we need any more evidence that his financial success has nothing to do with intelligence?
Elon Musk is intelligent, intelligent people make mistakes and believe in weird shit all the time
DominusOfMegadeusMusk maintains that camera-only technology is the most “human” way to approach self-driving, since people use their eyes to navigate the road.
Newsflash for you, Elon. Most people are terrible drivers. We should be striving to do better as a society, not imitate something that already sucks.
He also claimed he wanted to make self driving safer than humans. You can't do that well if the car has the same visual limitations a human has.
Well the computer could probably react faster than a human even with the same visual stats.
SkunkWorkzOf course computers can "compute" faster than humans. In that case, safety should not be compared with the average human. We should be expecting a lot better. It can also fail faster, and in unpredictable ways, than a human depending on the condition, which is why you can't skimp out on sensors.
RhaedasWhen Autopilot started I would hear people joke about how it couldn't drive in bad weather where people could. They seem to miss the point that when the computer begins to lose information needed to navigate, it's going to stop driving. People lose information and they keep going. One of these is safer.
Of course if Elon had thrown everything at the car to make it have information even in terrible or odd conditions, there'd be more merit in claiming those cars are safer than humans. But between genius brain (however much there is) and narcissist, the latter won out in doing it his way because others were doing it the obvious way.
The safest roads would be fully automated and tapped into each other. We wouldn't even need lights at intersections. A hybrid mix of human/computer traffic is always going to be dangerous.
If you make a road safe enough you end up with trains.
Indeed. We might have gone that way. Lots of larger cities had rail for their public transit, but the car industry got that removed for obvious reasons.
They seem to miss the point that when the computer begins to lose information needed to navigate, it’s going to stop driving.
There's also the point that, while AI has gotten quite far, the human brain is still fairly superior at accurately interpolating and interpreting limited information. This may have changed in the past year or two, but my impression is that humans are still far better than machines at handling new or "corrupted" information, like driving in poor visibility, or suddenly having road markings disappear, etc.
Except:
- When mud, snow, bug splatters, etc. blinds a camera I can very likely still see perfectly fine out of clear part of the windshield. I can move my eyes, the camera can’t move.
- Sun glare will blind some cameras (even side cameras) when it’s low in the sky. The same sun wont bother me at all.
- I’ve seen the cameras get tricked by things in front of it like a trailer full of tree branches & other landscaping debris that hangs over the back and obscures the brake lights & license plate.
Your points illustrate why other means besides cameras should be also used, as well as why the human brain's ability to filter or even ignore things is a bonus to our driving ability. Or a detriment. People who power through bad weather or sun glare or any other obstacles that obscure them seeing well and manage to get through aren't greater than the computer driver, they're just lucky. Same can be said for all the people driving while on the phone, they aren't skilled in multitasking while moving hundreds of feet per second, they just happen to have it clear 99% of the time so think they're that good.
The main point was that computers need all the information they can get to compete with humans, but they also have the ability to get data we cannot, and it's stupid to not give them that ability because of some desire to simulate the full (read that as limited) human experience. Humans deal with less info all the time, but that doesn't make them better.
Agreed.
I hate trump and Musk and I morn the world we could have if it weren't for people like them. However... after the election the only bit of hope that I - and which I knew would never happen - was that maybe they would use their authoritarianism to make the very hard decisions that could lead to a better society, such as phasing out human operated vehicles on public roads in favor of interconnected, self-driving vehicles. We have the technology to do so many amazing things... there just isn't enough profit to bribe the politicians, pay the executives and build it to make it worth while.
Benevolent dictators almost always happen only in fiction, and they don't last. I guess you can get some that do a few good things while being bad overall.
Oh, I know, and I know it was an absolute dumb thing to even think would be in the realm of possibility, but I was just trying to find something, anything to grab on to and help keep my hope on the ventilator.
The best I'm hoping for now is that trump will do something good on accident, like how he legalized thc in 2018. Sure, he did it in the stupidest way possible, but it's something.
Random drunk walk is sometimes successful in the results. The bonus is that it also prevents some malevolent actions from succeeding.
Musk maintains that camera-only technology is the most “human” way to approach self-driving, since people use their eyes to navigate the road.
A few years ago I was driving on the motorway, came up on a bend in the road and was greeted by a dense freak fog bank out of nowhere. I immediately let go of the accelerator to reduce speed, at the same time my dashboard lit up like a Christmas tree and a collision alert started blaring. That gave me enough time to apply the brakes and prevent a collision with the first and only traffic jam I've ever seen there.
I see no reason to not augment our own capabilities with radar and lidar, to see what we as humans can't.
Imagine if we could “see” in those wavelengths!
…
Don’t tell Musk I said that
Now hiring for experimental brain surgery subjects! Lots of money! Sign these twelve waivers.
This was him justifying what was a cost saving decision that became a face saving battle for him personally as everyone told him he was wrong.
If there is one thing Elon cannot stand above all others is admitting he was wrong, especially when he has spent years promising this and now he would have to retrofit at his cost Lidar to all those cars he sold as self driving ready with an expensive optional extra.
He might be able to avoid any sort of punishment from the US government as long as he stays in Trumps good books, but he will not be able to do so in Europe or similar.
waymo is already superior to tesla in self driving,waymo has been around for a few years already. teslas already too late into the game.
Nothing is lamer than superior technology, eh Elon? I mean you may be a looser but at least you're not a nerd.
FuglyDuckWhat’s funny here is that Tesla used all of the Tesla owners driving habits to train.
One thing this means is that when it’s “socially acceptable” to go +20mph it’s going to. Not that that makes it right, but what it also means is that they didn’t sanitize their data.
So think of the worst Tesla driver you know. They helped train FSD.
There is a segment of highway near Budapest where cops often hang out on an overpass with a speed camera. Teslas do a light phantom brake under that overpass, like going from speed limit to 80% speed limit, because apparently the car learned that that's what it should do there.
I wouldn't have believed it's that stupid, but there is a whole discussion on local owner groups about that specific spot, and I've also seen it first hand from the passenger seat.
Just to clarify…
How bad is Budapest traffic? Is it LA? Or New Jersey?
Most drivers are good at driving, terrible at being good people. So it's not like you get cut off a lot, and there is less texting and driving than in other places, but there are more people road raging. I've seen someone getting brake checked by police, and I've also seen someone brake checking police.
Traffic jams happen, but it's not LA level. The roads are terrible though. The motorway that this thing is on is notoriously unsafe because it has much tighter turns that it should have, and it's rated 110 kmh rather than 130 as a result, and that is still too fast.
Most drivers are good at driving,
[x] doubt. :P
but that's just because I assume everyone is a terrible driver. Around here, we have people struggling with the whole zipper merge thing, though.
Relevant:
I mean the data IS sanitized, but not to the level that would have required certain human things to not happen.
Part of what's led to its improvement over the years is better going through the data and removing bad things or properly labeling them.
That left turn that was cut to short makes it into the first set of training as a cursory look at it seemed okay, and then they see that cars are cutting turns to short. So they go through the data again and try to find examples of it and then label them properly so it doesn't think it's okay.
But that's not a simple process, and then trying to only have certain good behaviors gets really hard because they're actually very uncommon in normal driving because the bad behavior is socially acceptable.
You can establish rules in top of the neural net output. No acceleration higher than 0.3g. No speed higher than the limit + 5 (if you know what the limit is, which teslas struggle with to this day). No running of red lights.
LungThe thing is that you have to break the law to be an effective and even safe driver. Going way under the limit or refusing to go into the opposite lane for a moment means that you cause traffic congestion and piss people off. Waymos definitely break laws at times, I've seen it personally. And other times waymos get too "safe" and end up locked in place for 30 min at a time. The real world is a chaotic place and there's always been a discrepancy between what the laws are and how people actually drive. Lidar helps see things humans cant, but the main problem is the intelligence required, which may improve over time
The biggest problem is if you’re training in the extremes.
And they did.
The stopping for 30 minutes has more to do with “I don’t know”, which is something Tesla could do more of, imo. (And certainly not in the way they just set you up for a crash and hand it over after it’s too late.)
GhostalmediaThe worst Telsa driver I know. Hum. That’s a tough competition.
LiDAR is fucking awesome, actually. There's some LiDAR data on USGS website for free that shows high detail aerial geographic height-maps, I once used some to create a 3D model of a beach in California.
The only viable competition to LIDAR is structured light (see Leap Motion, there's equivalent sensors for cars), which uses an IR source with patterned light and multiple high frame rate cameras to calculate depth from the reflections. In theory light field photography with special lenses is possible too, but far more computationally heavy for real-time use IIRC
There's some safety issues with LIDAR at close range (it's a laser! it can damage cameras, etc), which is basically the main reason to not use it. But Tesla are dumb enough to try to replace them with cameras alone, and not even using proper multi-camera techniques to calculate depth
Can it really cause damage? Lidar is flown constantly, and all of googles street view had been ran with lidar. That's millions of miles of data collection and I haven't heard of any negative effects. I get that it is a laser, but is duration and distance must be big factors.
Not saying you are wrong, just looking to quanitfy the risks.
WiddershinsYou mean to say the cars of the future can take out security cameras. That's not a negative. Security cameras are the surveillance state. If you want to take them out with today's cars you've gotta ram them and bang out the dents in your car.
Thanks for the article. That is interesting. It also is confusing that they wrote "Lidar is not the only thing that can damage camera sensors – lasers are just as harmful." Uh...Lidar is Laser.
But it is in so many fields, even devices with cameras. Apple has been adding Lidar to their phones/tablets for 5 years now. Why is this an issue now? Like I said, there is a TON of Lidar in use everyday.
Cars use stronger LIDAR lasers than the phones. The bigger range and faster response time requires it.
BeBopALouieSo stupid to deride a technology that a computer can process far better than video alone. Its only because he can't own and monetize it.
Frenchfryenjoyer (she/her)This is the same guy who said (paraphrased) "they do it with 4 bolts so why can't I do it with just 2?"
pjwestinHe meant expensive.

TIL Guardian reporters watch Diggnation.
"LIDAR is so lame! Who needs to be able to accurately map their surroundings, when our cars can get confused by a shadow passing across one of their lenses, just like humans do? It's so much more efficient to be blinded by fog, or low light conditions."
Someone who thinks laser is lame is a huge moron. Case in point.
Other end of the scale: styropyro
Let's organize a 1Vs1 !
I keep insisting he'll kill us all one day, and it'll look freaking awesome for the milliseconds before we go blind then die in laser fire 😂
With good integrated design, the LIDAR could be practically invisible. So weird to think the average person actually would care about the details of how something works, or maybe Elon Musk just literally cannot imagine a car that uses LIDAR without it having a big assembly on the roof.
Compared to the Cybertruck's design, I don't think having a LIDAR antenna on top of the car is so bad.

I also much prefer my robot to not send a live camera feed to some Chinese server. So even if Lidar were to be less good I’d opt for that.
I'm absolutely not going to buy a mapping robot vacuum unless it keeps that info local, or on a server I can host. I have one right now with cloud controls, but it's only for the schedule.
Looking at their recent facelifts, I don't think they have many good designers left
I have a theory on this. They use a lot of ML for FSD and Ap. That a radical redesign would change the model enough that they would have to retrain from scratch. So they keep the facelifts extremely minor .
Just a theory.
Tesla's used to have LiDAR - they turned them off in software and stopped adding them to newer models.
Yeah, it's really all just cost savings. On their overpriced "luxury" cars
A long time ago Elon promised that full self-driving would be coming to existing cars that had their self-driving package installed which was cameras only. Elon is probably sticking with cameras only to avoid a lawsuit.
They stuck the model Y's new added front camera right under the "grille" shape (where the black trim ends and body colored panels begin), so the rest of it being so bland doesn't have an excuse. The rest of it's front cameras are under the front glass, they could at least make an interesting fascia, even if they had to keep the dimensions roughly the same
This has nothing to do with aesthetics and everything to do with reducing production costs. The sensors themselves add to costs, but then the data processing for all of this data adds to the computational needs of the system, sensor installs requiring calibration and flexibility for changes in sensors add costs. The list goes on.
Musk and Tesla are standing firm on their position that LiDAR is needless and that others will follow their lead here, but so far in practice the lack of LiDAR in Tesla vehicles has shown to be a serious disadvantage compared to other systems.
Teslas are built cheap.
Our eyes are not perfect organs so why pretend like they are? Our eyes fail us:
Why wouldn’t we want more incoming data to account for these shortcomings? Optical-only vision-based solutions are incomplete because our eyes are incomplete. I can’t see that a car is stopped dead in the road 10 feet ahead of me in thick fog, but an advanced set of telemetry sensors can. My eyes are not better than the scores of technology we’ve built over the past few decades and I’ve been practicing with them for 46 years. Give me a helmet that includes LIDAR and infrared and night vision and sonar and telemetry from a satellite and GPS and weather tracking and god knows what else and I’ll be much less likely to rear end that car in the fog. We humans invent technology to make up for our shortcomings, so why go with the idea of “if it’s good enough for biological evolution it’s good enough for these multi-ton contraptions we have hurtling down highways next to each other several metres apart at 100 km per hour every second of every day?” It sounds ludicrous on its face. We can choke on a peanut because our swallow tube is the next to the breathing tube ffs. We can do better.
Yeah, the "appeal to nature" fallacy that Musk is using is really dangerous. I want the best tools that are practical for the job, since this has actual life and death consequences. A mix of sensors that work together and covers each others limitations.
People built houses before hammers were invented. But that's sort of the point of tools: that they can do things more efficiently than we can.
Unless we figure out who would "personally" be liable when an accident happen we should not have any self driving cars on the street.
Right now if someone crash into my car I know who is liable.
If self driving car crash into my car, are you telling me to sue Tesla? Lol, as if that is feasible.
Always interesting to see the view of the degree of Elon Musk's involvement in his companies' decisions swing depending on whether the outcome is good or bad.
Not sure what you mean. He's always been pretty involved in Tesla designs.
What I mean is that when Musk-owned companies have successes people are very often quick to accuse him of "just hiring smart people" or "just buying a successful company." It's only when those companies have failures that he gets credit for being hands-on in their design decisions.
Don't get me wrong, I think Elon Musk is a pretty terrible person both in terms of his personality and his politics. But pretty terrible people can nevertheless be smart and make good engineering decisions. Just look at von Braun as a prime example.
I think it is more nuanced than that. He has had a variable amount of involvement in multiple companies throughout the years, and noting when something is or is not his fault is not a bad thing.
Like I said before, he has been pretty heavily involved in Tesla since he bought the company. He notably makes a lot of decisions. SpaceX, on the other hand, is notably run by Gwynne Shotwell for a majority of decisions. He has made some design decisions, but he is pretty checked out on the day to day.
I don't think he was never a good engineer, but I think he has not done it in so long, that he has lost those skills. Also, if the alleged amount of ketamine he does is even kind of accurate, that does not help make good decisions. He also has almost nobody he will listen to. We can see all that reflected in the decline of good ideas coming out of Tesla (again, the company he is most involved in).
Calling Musk an engineer is like saying the same about Steve Jobs. Both are(/were) salesmen happy to claim credit for every success while delegating blame for problems.
Not that this is unique to the pair in the current climate of people believing in messianic oligarchs, but I'm not really aware of any boots-on-the-ground innovation that sprang forth from Musk's mind. The Cybertruck is a fucking joke, and that seems to be the thing at Tesla he was most involved in of late, then broke the windows during a demo.
Leave breaking Windows at a keynote to Steve Ballmer.
I think at one point he was a software engineer. I don't he has been that for a long time, though. This is also probably not true any longer, but he did have a knack for spotting up and coming companies and buying them.
The Cybertruck is definitely the epitome of Musk's current "skills"
It's entirely possible he was responsible for some of PayPal, but since, his MO has been, as you said, buying up promising companies. And there's nothing wrong with that. The problem comes when he rewrites history to be the founder instead of simply an investor in these firms and claims credit for shit he simply didn't do.
I fell for it myself for a while. Early days of Tesla, early days of SpaceX ... dude knows how to sell and arguably accelerated BEVs, but it appears he doesn't know how to actually carve tunnels or rewrite mass transit with functionally unlimited money. Not to mention, Starship is having a really bad time these days, which stands in stark contrast to how banal Falcon launches have become.
His particular degree of involvement in this decision has been well documented for years, long before the consequences of those decisions.

Sure, not disputing that. I'm more annoyed by the double standard regarding his successful decisions.
That's being too nice, the CEO is clearly proud of not mapping cities, as seen in the tweets. The journalist should call it out explicitly. "They are probably not mapping as suggested by the CEO's public posts." That's not too much of a leap.
