In the piece — titled “Can You Fool a Self Driving Car?” — Rober found that a Tesla car on Autopilot was fooled by a Wile E. Coyote-style wall painted to look like the road ahead of it, with the electric vehicle plowing right through it instead of stopping.
The footage was damning enough, with slow-motion clips showing the car not only crashing through the styrofoam wall but also a mannequin of a child. The Tesla was also fooled by simulated rain and fog.
…what is your point here, exactly? The stakes might be lower for a vacuum cleaner, sure, but lidar - or a similar time-of-flight system - is the only consistent way of mapping environmental geometry. It doesn’t matter if that’s a dining room full of tables and chairs, or a pedestrian crossing full of children.
I think you’re suffering from not knowing what you don’t know.
Let me make it a but clearer for you to make a fair answer.
Take a .25mw lidar sensor off a vacuum, take it outdoors and scan an intersection.
Will that laser be visible to the sensor?
is it spinning fast enough to track a kid moving in to an intersection when you’re traveling at 73 feet per second?
You’re mischaracterizing their point. Nobody is saying take the exact piece of equipment, put it in the vehicle and PRESTO. That’d be like asking why the vacuum battery can’t power the car. Because duh.
The point is if such a novelty, inconsequential item that doesn’t have any kind of life safety requirements can employ a class of technology that would prevent adverse effects, why the fuck doesn’t the vehicle? This is a design flaw of Teslas, pure and simple.
Older teslas HAD lidar. They were removed on newer models to cut costs.
They did not. They had radar, which was removed.
But they do, there are literally cars out there with lidar sensors.
The question was why can’t I have a lidar sensor on my car if my $150 vacuum has one. The lidar sensor for a car is more than $150.
You don’t have one because there are expensive at that size and update frequency. Sensors that are capable of outdoor mapping at high speed cost the price of a small car.
The manufacturers suspect and probably rightfully so that people don’t want to pay an extra 10 - 30 grand for an array of sensors.
The technology readily exists rober had one in his video that he used to scan a roller coaster. It’s not some conspiracy that you don’t have it on cars and it’s not like it’s not capable of being done because waymo does it all the time.
There’s a reason why waymo doesn’t use smaller sensors they use the minimum of what works well. Which is expensive, which people looking at a mid-range car don’t want to take on the extra cost, hence it’s not available
Only Tesla does not use radar with their control systems. Every single other manufacturer uses radar control mixed with the camera system. The Tesla system is garbage.
The self driving system uber was working on also went downhill after they went full visual only.
yeah, you’d think they’d at least use radar. That’s cheap AF. It’s like someone there said I have this hill to die on, I bet we can do it all with cameras.
Yeahhh pretty sure I know who
Not sure it’s a him thing, though it definitely could be. An inexpensive Chinese radar element could have eliminated all these problems and they could still use cameras as the main system. It would have cost them dollars to add it to the parts list and it’s just a minor input to the collision avoidance stuff.
I would expect him to do a cost-savings thing and pull parts, but they’re not really all that cost adverse. ( until you get to QC )
Maybe it was a DOGE kid he hired to come up with ideas or something. Doing with cameras only is more like a technical challenge, nobody looks at that and goes, WOW they can just do that with cameras, they go wow, that’s a horrible idea full of dust, dirt and mud issues.
That said, he has made worse plans :)
Your perspective is very generous to Elon. “It’s a cheap part, why would they omit it? Probably it was some dumb kid working there”.
Usually cost-cutting measures that make significant compromises are top-down pushes, profit is their concern. Might not have been the CEO himself but, in my perspective, it would have been from the top levels.
How are people still giving this man a fucking pass on everything?
August 2019:
Elon Musk: “Anyone relying on lidar is doomed.” Experts: Maybe not
Jan 2025:
Tesla CEO Elon Musk Dismisses LiDAR Again: ‘Humans Drive Without Shooting Lasers Out Of Their Eyes’
It was Elon, he was very vocal about how Lidar was an expensive crutch and how machine learning would get so much better than human vision back around 2016ish.
Good God it’s like you’re going out of the way to intentionally misunderstand the point.
Nobody is saying that the lidar on a car should cost the same as a lidar on a vacuum cleaner. What everyone is saying is that if the company that makes vacuum cleaners thinks it’s important enough to put lidar on, surely you’re not the company that makes cars should think that it’s important enough to put lidar on.
Stop being deliberately dense.
Its weaponized incompetence.
I bet they do the same shit with their partner when it comes to dishes, laundry, and the garbage.
lol, what partner
You’re either taking to a fanboy or Elon on ket. You ain’t gettin’ through.
I’m not being deliberately dense it just a seriously incomplete analogy. At worst I’m being pedantic. And if that’s the case I apologize.
I agree with the premise that the cars need lidar radar whatever the f*** they can get.
Saying if a vacuum company can see that a vacuum needs lidar (which is a flawed premise because half the f****** vacuums use vslam/cameras) then why doesn’t my car have lidar, none of the consumer car companies are using it (yet anyway). It’s great to get the rabble up and say why are vacuum companies doing it when car companies can’t but when nobody’s doing it there are reasons. Ford Chevy BMW f***, what about Audi what about Porsche? What about these luxury brands that cost an arm and three fucking legs.
Let’s turn this on its head, why do people think they’re not including it in cars. And let’s discount musk for the moment because we already know he’s a fucking idiot that never had an original idea in his life and answer why it isn’t in any other brand.
Is it just that none of these companies thought about it? Is it a conspiracy? What do people think here. If I’m being so dense tell me why the companies aren’t using it.
You mean company singular. It’s literally only Tesla that don’t use lidar every other car manufacturer uses it. So the answer is because Elon wants to save every last single penny. There is no grand conspiracy here for you to uncover it is literally that Tesla are cheapskates.
And you are being deliberately dense because this has been explained to you ad infinitum and you still don’t seem to get it.
I’ve not seen any of that in the wild around me. Car sales are kinda shit in the US for the past year tho. guess I’m behind on what’s out there. Economy what it is it’s been a couple years since I’ve looked at getting a car.
It’s a cost-benefit calculation.
So the question is whether they can achieve self-driving without it: humans rely on vision alone so maybe an ai can. I’m just happy someone is taking a different approach rather than the follow the pack mentality: we’re more likely to get something that works
Edit: everyone talks about the cost-benefit, but I imagine it makes things simpler for the ai when all sensors can be treated and weighted identically. Whether this is a benefit or disadvantage will eventually become clear
Whether lidars are reliable enough to run on autonomous cars has nothing to do with whether they are cost efficient enough to run on vacuum cleaners though. The comparison is therefore completely irrelevant. Might as well complain that jet fighters don’t allow sharing on Instagram your location, because your much cheaper phone does.
You’re bending over backwards to miss the point huh
So be clear about the point.
That’s like asking me to explain to you why 2+2=4
If you’re incapable of seeing how obtuse you’re being its either deliberate, or you’re mind numbingly dumb
i see so you don’t know either, just trying to upset me, heh GL with that
what’s your point again?
As a third party in this conversation: can you please re-read the conversation? It seems like you’ve misunderstood almost everything that was talked about
Nah, someone can actually articulate the problem clearly or I’m not going to deal. 20 brigading accounts saying I’m incapable is nothing more than a troll.
So far, I’ve just had people double back and be vague.
Your take on what’s happening here is funny… you’re not being brigaded, you’re not being targeted by one guy with a bunch of alts. You said something stupid and dickheaded, and tons of people are trying to point that out to you, but you’re doubling down on being dickheaded and stupid.
But no, it’s everyone else that’s wrong. Do yourself a favor and just stop replying to the thread.
Decent LIDAR sensors have gotten a lot cheaper in the last 5 years or so, here’s one that is used in commercial self-driving taxis: https://www.alibaba.com/product-detail/X01-36020021-Nev-Auto-Parts-for_1601252480285.html
So that one sensor is $700. Waymo has 4 LIDAR sensors (all of which are physically larger and I would imagine fancier than the Alibaba ones, but that’s speculation), so just in the scanner hardware itself you’re looking at $2,800. Plus the computer to run it, plus the 6 radar receivers, and 13 cameras, I could absolutely see the price for the end user to be around $10k worth of sensors.
But to be clear, I don’t think camera only systems are viable or safe. They should at minimum be forced to use radar in combination with their cameras. In fact I actually trust radar more than lidar because it’s much less susceptible to heavy snow or rain.
Shit that’s pretty decent. That looks like a ready fit car part, I wonder what vehicle it’s for. Kind of sucks that it only faces One direction but at that price four them would not be a big deal
I can’t find what it goes to, but it looks like Baidu and the US company Zoox use them in their robotaxis.
Edit: Lixiang models L9, L8, and L7 use that sensor.
The price of lidar sensors has dropped by like 50 times since musk decided to cut costs by eliminating theny from their cars.
Yeah looks like it, chinese sensors are down to 700 a pop. Even if it’s a few grand, it’s decent, looks like chevy offers it on 7 models.
and I think you’re suffering from being an arrogant sack of dicks who doesn’t like being called out on their poor communication skills and, through either a lack of self-awareness or an unwarranted overabundance of self-confidence, projects their own flaws on others. But for the more receptive types who want to learn more, here’s Syed Saad ul Hassan’s very well-written 2022 paper on practical applications, titled Lidar Sensor in Autonomous Vehicles which I found also serves as neat primer of lidar in general..
Wow, what’s with all the hostility against him.
It’s maybe because i also know a bit about lidars that his comment was clear to me (“ha, try putting a vacuum lidar in a car and see if it can do anything useful outside at the speeds & range a car needs”).
Is it that much of an issue if someone is a bit snarky when pointing out the false equivalence of “my 500$ vacuum has a lidar, but a tesla doesn’t? harharhar”.
Because no one suggested that.
So someone saying “why does my 500$ vacuum have a lidar but not the car” isn’t suggesting that?
I guess in some technical way you’re right, but it for sure is the implication…
Well look at you being adult and using big words instead of just insulting people. Not even going to wastime on people like you, I’m going to block you and move on and hope that everyone else does the same so you can sit in your own quiet little world wondering why no one likes you.
You’re an idiot.
jesus man, how many alts do you have?
