Tesla Autopilot drives into Wile E Coyote fake road wall in camera vs lidar test
Tesla Autopilot drove into Wile E. Coyote-style fake road wall in the middle of the road in a camera versus lidar test.
While most companies developing self-driving technologies have been using a mix of sensors (cameras, radar, lidar, and ultrasonic), Tesla insists on only using cameras.
The automaker removed radars from its vehicle lineup and even deactivated radars already installed in existing vehicles.
I did not know about this. I thought they were also using a mix of sensors, since they originally were. But they stopped putting them in new ones and even disabled them on vehicles that already had them?!
This is some next level stupidity.
A while ago people called Musk out on only using cameras when better options existed(for reasons exactly like this one), and he had a little tanty about it like the normal adult man he is. I have no doubt turning off existing radar features is a spiteful move because he got his feelings hurt.
Yeah this is the reason Tesla is massively overvalued. Self drive tech won't be coming from Tesla because Musk interfered and told his engineers to remove lidar.
Musk is nothing but an investor but he believes his own nonsense about being a genius. He made some good bets but he also made some bad ones (Twitter being one) and Tesla is not going to justify irs crazy shareprice. Even having fallen 50% from peak it is way overvalued.
All true, but I think Twitter was a “good” bet. He controls a surprisingly large amount of the media landscape now and it got his bff rapist in chief elected.
RADAR*
he also made some bad ones (Twitter being one)
He paid $44M and it made him >$100B richer, it seems like a smart bet to me.
Anywhere Tesla can cut corners and save money, they do. The real reason they don't use it is lidar is expensive but lying about self driving is free.
Why have more data when you can crash through walls with less data?
It's fine... If you're a road runner and not a coyote. Meep meep!
Now imagine what the boy genius is doing for the us govt.
The comments say that the tests weren’t exactly right. Something about not using FSD after stating their were going to.
I think it shouldn’t matter, the other vehicle using FSD and didn’t murder a bunch of fake children.
Supposedly there's a difference between 'Full Self Driving' and 'Autopilot' (the later is what Mark used in the video). I'm not convinced there's any meaningful difference for a test like this though.
Changing the software behind them isn't going to magically give cameras the power to see through visual hindrances like rain/fog, or detect range to a nearby object that appears far away (like a painted wall).
There is a huge difference between Autopilot (basically hasn't been updated in like four years) and FSD. Autopilot is basically just glorified lane keeping while FSD attempts to drive end to end (stop signs, traffic lights, etc.).
Not sure how it would change this test though. FSD is much more vision based than Autopilot.
Mark states he used it because it was more conservative but commenters are saying it wasn’t on for the wall test.
This is hilarious. It wasn't even a front on photo of the road but a perspective corrected on, for the side on, wile e coyote perspective shot. Head on, the photo would look like it took a sudden, immediate corner, not even a curve. Tesla's software just said 'this is perfectly normal'.
its vision plus neural net system is designed to work like a human driver
Looks at street death toll.
The problem is that at scale you can’t have every car on the road using lidar at the same time.
They’ll mess with each other’s systems.
Same with radar.
So while this seems like a solved answer, it’s not necessarily as simple as it sounds
This is objectively false. Early lidar systems did have crosstalk interference and mitigations have been designed and working for years.
It's like saying you can't have WiFi cause if all your neighbors do it won't work. As these systems hit the real world mitigations get designed to handle these types of issues.
Again, also not true. Lidar and Radar systems use a special spread spectrum frequency modulation and they do not interfere with each other.
I’m not sure that’s true. Has anyone punished a study on this? Lidar has far less “on” time than one would think.
IMO what is required is stereoscopic image capture and processing - This allows instant distance measurement to every pixel of the image
