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.
My 500$ robot vacuum has LiDAR, meanwhile these 50k pieces of shit don’t 😂
Holy shit, I knew I’d heard this word before. My Chinese robot vacuum cleaner has more technology than a tesla hahahahaha
Vacuum doesn’t run outdoors and accidentally running into a wall doesn’t generate lawsuits.
But, yes, any self-driving cars should absolutely be required to have lidar. I don’t think you could find any professional in the field that would argue that lidar is the proper tool for this.
…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.
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
https://techcrunch.com/2019/03/06/waymo-to-start-selling-standalone-lidar-sensors/
This article is six years old, so I wouldn’t be surprised if they’re even cheaper now.
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.
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
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
Prices tend to come down on these things simply because the car industry widely adopts them. For example, accelerometers became cheap because they were needed for air bags. LIDAR might not come down as much as those have, but it won’t be tens of thousands of dollars.
Older teslas HAD lidar. They were removed on newer models to cut costs.
They did not. They had radar, which was removed.
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..
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?
Hey if everyone you meet is an asshole, maybe they have lots of alts. But that’s not usually how that sentence ends.
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…
So they think self-driving cars should have lidar, like a vacuum cleaner. They agree, and think it’s a good idea, right?
…then in the next sentence goes on to say that lidar is not the correct tool. In the space of a paragraph they make two points which directly contradict one-another. Hence my response:
They could have said “oops, typo!” or something but, no, instead they went full on-condescending:
I stand by my response:
And while I’m not naive enough to believe that upvotes and downvotes are any kind of arbiter of objective truth, they at least seem to suggest, in this case, that my interpretation is broadly in line with the majority.
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.

I think it was a guess 🤷♂️ or maybe it’s a different currency?
