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.
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
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.
Humans don't drive on sight alone.
Uhhhh... What the fuck else are the rest of you using?!
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.
One obvious sense is hearing, as in hearing things like sirens to move out of the way.
My probing cane.
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.
Sound? Though I guess all the fancy expensive cars remove this feedback
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.
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.
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.
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.
No it isn't. Anywhere in the world the vast majority of crashes are caused by negligence, speeding, distraction, all factors that can be avoided without increasing our depth perception accuracy.
A lot of LIDAR fans here for some reason, but you're absolutely right.
There's just not a good amount of evidence pointing that accurate depth perception only obtained through LIDAR is required for self driving, and it also won't solve the complex navigation of a real world scenario. A set of visible spectrum cameras over time can reconstruct a 3D environment well enough for navigation and it's quite literally what Tesla's FSD does.
I don't know why someone would still say it's not possible when we already have an example running in production.
"But Tesla FSD has a high disengagement rate" - for now, yes. But these scenarios are more often possible to be solved by high definition maps than by LIDAR. For anyone that disagrees, go to youtube, choose a recent video of Tesla's FSD and try to find a scenario where a disengagement would have been avoided by LIDAR only.
There are many parts missing for a complete autonomous driving experience. LIDAR is not one of them.
