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.

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?

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..

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.

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".

But, yes, any self-driving cars should absolutely be required to have lidar.

So they think self-driving cars should have lidar, like a vacuum cleaner. They agree, and think it's a good idea, right?

I don't think you could find any professional in the field that would argue that lidar is the proper tool for this.

...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:

What is your point here, exactly?

They could have said "oops, typo!" or something but, no, instead they went full on-condescending:

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

I stand by my response:

arrogant sack of dicks

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.
