Even with LIDAR there are just too many edge cases for me to ever trust a self driving car that uses current-day computing technology. Just a few situations I’ve been in that I think a FSD system would have trouble with:
I pulled up at a red light where a construction crew was working on the side of the road. They had a police detail with them. As I was was watching the red light the cop walked up to my passenger side and yelled “Go!” at me. Since I was looking at the light I didn’t see him trying to wave me through the intersection. How would a car know to drive through a red light if a cop was there telling you to?
I’ve seen cars drive the wrong way down a one way street because the far end was blocked due to construction and backtracking was the only way out. (Residents were told to drive out the wrong way) Would a self driving car just drive down to the construction site and wait for hours for them to finish?
I’ve seen more than one GPS want to route cars improperly. In some cases it thinks a practically impassible dirt track is a paved road. In other cases I’ve seen chains and concrete barriers block intersections that cities/towns have determined traffic shouldn’t be going through.
Musk’s vision is (was?) to eventually turn Tesla’s into driverless robo-taxis. At one point he even said he could see regular Tesla owners letting their cars drive around like automated Ubers, making money for them, instead of sitting idle in garages.
Well FSD is supposed to be Level 5 according to the marketing and description when it went on sale. Of course, we know Tesla’s lawyers told California that they have nothing more than Level 2, have not timeline to begin building anything beyond Level 2, and that the entire house of cards hinges on courts and regulators continuing to turn a blind eye.
Or there are better other ways to tell a FSD car that the road is closed. We could use QR code or something like that which includes info about blockade, where you can drive around it, and how long it will stay blocked.
A FSD should be connected enough to call home and give info to the servers, those then update the other FSD cars, et voila tadaa.
Why should it get obscured? Just plug that giant QR code there. You can create QR codes, where you only need to see very little of the square to get all the info in the QR code. I don’t feel like obscuring would be any problem.
Mud for one. Trees and bushes for another. Strong wind for a third. All of those things already obscure signs or make them very hard for humans to read, let alone a computer.
I don’t know why people are so quick to defend the need of LIDAR when it’s clear the challenges in self driving are not with data acquisition.
Sure, there are a few corner cases that it would perform better than visual cameras, but a new array of sensors won’t solve self driving. Similarly, the lack of LIDAR does not forbid self driving, otherwise we wouldn’t be able to drive either.
challenges in self driving are not with data acquisition.
What?!?! Of course it is.
We can already run all this shit through a simulator and it works great, but that’s because the computer knows the exact position, orientation, velocity of every object in a scene.
In the real world, the underlying problem is the computer doesn’t know what’s around it, and what those things around doing or going to do.
It’s 100% a data acquisition problem.
Source? I do autonomous vehicle control for a living. In environments much more complicated than a paved road with accepted set rules.
K and KA band are used for blind spot monitoring and would make radar detectors go nuts until filtering got worked out, cars that use Lidar will set them off as well though they’re more rare still
Do you have lidar on your head? No, yet you’re able to drive with just two cameras on your face. So no lidar isn’t required. Not that driving in a very dynamic world isn’t very difficult for computers to do, it’s not a matter of if, it’s just a matter of time.
Would lidar allow “super human” driving abilities? Like seeing through fog and in every direction in the dark, sure. But it’s not required for the job at hand.
I have no idea what sense of balance has to do with driving a car and even deaf people can get a driver’s license but okay. How’s this an argument for LIDAR again? It does not have anything to do with either of those things.
That’s like asking what the human equivalent of a GPU is. There isn’t one nor would there be because humans and computers are fundamentally different things.
I remember watching a video talking about is there a camera that can see as well as a human eye. The resolution was there are cameras that see close but not as well and they are very big and expensive and the human brain filters much of it without you realizing. I think it could be done with a camera or two but I think we are not close to the technology for the near future.
You have eyes that are way more amazing than any cameras that are used in self driving, with stereoscopic vision, on a movable platform, and most importantly, controlled via a biological brain with millions of years of evolution behind it.
I’m sorry, you can’t attach a couple cameras to a processor, add some neural nets, and think it’s anything close to your brain and eyes.
Without LIDAR, this is a fool’s endeavor.
I wish this was talked about every single time the subject came up.
Responsible, technologically progressive companies have been developing excellent, safe, self-driving car technology for decades now.
Elon Musk is eviscerating the reputation of automated vehicles with his idiocy and arrogance. They don’t all suck, but Tesla sure sucks.

Temporary detour or road closure signs?
In my opinion, FSD isn’t attempting to solve any of those problems. Those will require human intervention for the foreseeable future.
Musk’s vision is (was?) to eventually turn Tesla’s into driverless robo-taxis. At one point he even said he could see regular Tesla owners letting their cars drive around like automated Ubers, making money for them, instead of sitting idle in garages.
Musk is an idiot

Sure. A QR code. That couldn’t possibly get obscured.

Dont let them know about that I don’t want my radar detector flipping out for laser lol
what?
K and KA band are used for blind spot monitoring and would make radar detectors go nuts until filtering got worked out, cars that use Lidar will set them off as well though they’re more rare still
What?
What does Radar have anything to do with Lidar?
They are completely in different EM spectrums.
Also modern LIDAR is keyed in a way that LIDAR systems can’t interfere with other LIDAR systems.
Maybe because I dunno, it’s a detector? I’d love to try to explain it further but it seems like you’re being intentionally oblivious so why bother lol

Humans don’t drive on sight alone.
Uhhhh… What the fuck else are the rest of you using?!
My probing cane.
Senses to support your sight when driving? Hearing and Balance come to mind, in that order of importance as supporting senses.
I have no idea what sense of balance has to do with driving a car and even deaf people can get a driver’s license but okay. How’s this an argument for LIDAR again? It does not have anything to do with either of those things.
FSD
What’s the human equivalent for lidar then?
That’s like asking what the human equivalent of a GPU is. There isn’t one nor would there be because humans and computers are fundamentally different things.

The resolution was there are cameras that see close but not as well and they are very big and expensive and the human brain filters much of it without you realizing. I think it could be done with a camera or two but I think we are not close to the technology for the near future.
Do you have lidar on your head?
Nope,
And that’s exactly why humans crash. Constantly.
Even when paying attention.
They don’t have resolution in depth perception, nor the FOV.
You have eyes that are way more amazing than any cameras that are used in self driving, with stereoscopic vision, on a movable platform, and most importantly, controlled via a biological brain with millions of years of evolution behind it.
I’m sorry, you can’t attach a couple cameras to a processor, add some neural nets, and think it’s anything close to your brain and eyes.
And also, cameras don’t work that great at night. Lidar would provide better data.
Do you have CCDs in your head? No? This argument is always so broken it’s insane to see it still typed out as anything but sarcasm.
