Tesla Fans Furious at Video of Tesla Crashing Into Wall Painted Like Road (futurism.com)

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.

To be fair, if you were to construct a wall and paint it exactly like the road, people will run into it as well. That being said, tesla shouldn't rely on cameras

Yeah, the Roadrunner could easily skip by such barriers, frustrating the Coyote to no end. Tesla is not a Roadrunner.

It's a highly questionable approach that has raised concerns over Tesla trying to evade guilt by automatically turning off any possibly incriminating driver assistance features before a crash.

So, who's the YouTuber that's gonna test this out? Since Elmo has pushed his way into the government in order to quash any investigation into it.

Lol yeah they're "furious"

[–] [email protected] 6 points 13 hours ago

I have no clue what you're trying to say, but the significant amount of outrage a day or two later that I suddenly saw explode on Twitter was mind boggling to me. Couldn't tell if it was bots or morons but either way, people are big mad about the video.

My 500$ robot vacuum has LiDAR, meanwhile these 50k pieces of shit don't 😂

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?

I think you’re suffering from not knowing what you don’t know.

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..

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.

[+] [email protected] -11 points 12 hours ago (2 children)

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.
