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.
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.
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
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.
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?
