I remember elon saying something along the lines of his camera system being just as good and they thusly don't need to employ things like LIDAR.

Things that happen when you rely exclusively on optical sensors, i.e. cameras. But that's just cheaper, more money for Nazi Elon.
Are we reeeeally sure optical sensors with fast image recognition software are cheaper than LiDAR?
The hardware is, which is the important part at scale: even if the code is 10x more expensive when you sell millions of the car it becomes pennies/car
This would be hilarious if it weren't for shitty cars causing deaths.
That said, I always wondered why we don't find a system like RFID that could penetrate concrete and asphalt, and plant passive receivers in roads? We re-pave roads so damn often in this country (the U.S.) it seems like we could've knocked it out in the past couple of decades, minus our most rural areas.
I know RFID itself isn't strong enough, but I imagine that would've been an easier problem than figuring our complete self driving. Not to mention making GPS a secondary system for U.S. road travel in most cases.
Maybe it's just a dumb shower thought?
I have another idea: echolocation and laser measurement.
Echolocation is specifically audio based.
Lidar is a similar technique, but much more accurate and precise.
Project a grid of laser beam, read when the laser bounces back, you know the distance to that part of the grid.
I don't know the value of echolocation in this case, as I'm generally ignorant here, but it's straight wild to me that they went purely on visuals.
Tesla used to also have radar (and maybe lidar?) but they removed it as a cost cutting measure. If you ever see older videos of a Tesla slowing down or stopping due to a potential collision a few cars ahead, that's from before they switched to only relying on cameras. The collision avoidance was significantly better back then.
Turns out having radar is rather important..
It's dirt cheap, too. If this was a cost-cutting measure, it was a thoroughly idiotic one. Which feels like the mark... of a certain someone I can think of
Insurance fraud is going to bankrupt Tesla robotaxis faster than an incompetent CEO ever could.
There will be too many ways to defeat the cameras and not having LiDAR unlike the rest of the industry may prove to be found to be a failure of duty of care.
I remember Elon foolishly saying his cars don’t need radar or lidar. Even software-disabling radar in cars that already had the hardware.
Not even just his cars, he thinks the MILITARY, doesn't need radar and can just use cameras to spot and track stealth fighters.
He's a fucking lunatic.
As an augmentation, the ability to spot and track objects visually would be amazing.
But then planes just have to fly above 10k ft, and pretty much guaranteed cloud cover.
I mean his right, his cars don't need radar or lidar. They just drive into things.

My vacuum would pass that test... why is a Tesla worse at this?
In short because Elon (wrongly) believes you only need cameras, he made the claim people also drive with just 2 eyes.
The thing is, we recognize a truck with stickers of a stopsign, while AI vision gets confused.
Waymo (Googles self driving side hussle) was build on lidar and other sensors and has been using robot taxis for many years now in geofenced specific areas.

Lmao would it be illegal to put a stop sign on the back of your car?
Some school buses have a sticker / sign on the back that says "I stop for railroad crossings" and can have a stop sign on said sticker.
I was thinking the same thing. What would happen if you popped one out of the back of your car while driving in front of a self driving car on the freeway?

Make Elon test ride the first Tesla robotaxi and there's a chance the funniest thing of all time will happen.
TaxiGate? I just hope he takes along four or five billionaire friends with him.
This is why it's fucking stupid Tesla removed Lidar sensors and relies on cameras only.
But also who would want a tesla, fuck em
I was horrified when I learned that the autopilot relies entirely on cameras. Nope, nope, nope.

They never had lidarr. They used to have radar and uss but they decided "vision" was good enough. This conveniently occurred when they had supply chain issues during covid.

Some cartoon shit
Apparently they keep getting tickets in China because they didn't bother to adjust the settings to accommodate Chinese roads and traffic laws. Result is Tesla is getting utterly crushed by BYD in their one major market that doesn't care about Elon's antics.

Meep meep!
I am very glad that Elon and Trump have overreached and now Tesla is suffering. I hope Starlink is the next domino to fall.
Yup plus the European Union is making their alternative to launch in a year or 2

I seem to recall that fElon prevented the self driving team from utilizing LIDAR for any part of the system, instead demanding that everything run off of optical input. Does anyone else remember the same?

New stuff to add to the car kit bag for the 21st century
- poster board to block usonic weapons
- black paint, white paint, roller, brush to paint tunnels on walls
- orange cones to pen in self driving cars
And a "Yikes!" sign 🤣
There's a very simple solution to this. BUILD MORE TRAINS!
