I mean tons of technology outperforms humans by a mile... plenty of other computer vision systems already outperform people so not sure why Tesla would be exempt here due to 'evolution'.
Ultrasonic or radar or lidar sensors are much simpler solutions to the problem of computing distances, as they do not rely on computer vision.
Note that the reason this problem is very hard for computer vision is that there is simply not enough information in a 2D picture to get 3D distance information, even with parallax. Our eyes also can't solve this problem. Instead, our visual system uses numerous heuristics based on our inherent understanding of simple classical physics and the world around us.
For example, we recognize that a particular blob of color represents a car, and that cars are solid objects, where each part of the car moves at the same speed as each other part (this assumption breaks if something flies off the car). We recognize that objects throw shadows, and what effect shadows have on color, so we can very easily tell the contours of an object even if it's speckled in light and shadow. We also know what approximate sizes cars are, and that means we can immediately differentiate a far away car from a close one. We also know that cars sitting on the road are probably moving, while cars on the sidewalk are probably parked, and that again helps us estimate their movement based on relatively little data.
If you don't believe that depth perception is based on far more than parallax, just try to explain how come people/animals with a single eye can still estimate distances to a very good degree (not enough to be marksmen, but more than enough not to run into walls).
That is certainly false - perhaps with extremely limited amounts of parallax yes but that isn't how this setup is working. Humans certainly use heuristics not only because our brains are capable of it but also because a face only has a few mm of separation, with enough parallax you can get phenomenal 3d information out of a visual system. Replacing a single sensor here is certainly not too general for good performance but also my point again was never to say this was an optimal or perfect solution only to say evolutionary arguments are stupid here because we build machines and algorithms every day that operate better than evolution does.
Low speed, I'd figure about 10 mph tops: A softball to end all softballs for AEB, and somehow I got hit with considerable force. We've had radar based systems that would have avoided this since the 2000s.
I work in the self-driving space and while it's not an apples to apples comparison because of cost, all I could think is how our sensor stack would have allowed recognizing the car I stopped for, and probably the car it stopped for, let alone my car stopping.
I've already harped on how stupid the "FSD Beta" is, but I quite literally the absurdity of it shoved in my face just this morning only to come and read this. Why is Tesla even being allowed to run this circus at this point?
(it is crazy to me how many brands only have the good safety stuff as part of some ridiculous 9000$ sunroom and leather and Sirius xm package / trim ;-< )
Contrary to some of the replies, at low speeds AEB does override the accelerator, unlike the highway ACC component of AP, so it should have engaged.
I'm pretty sure my Subaru does the same. But I'm not brave enough to actually try a rear-end.
I've been thinking of getting a big cardboard box to try with, but so far it's only an idea :)
When these systems were new, many vehicles were only able to decrease collision speeds. These days, many vehicles completely avoid crashes at both 12 and 25mph.
Even a new base Honda Civic won’t hit the car in front of it at 25mph. (Or a pedestrian!). https://www.iihs.org/ratings/vehicle/honda/civic-4-door-hatc...
FWIW, Then unintentionally I had a bit of real world confirmation: a few months ago a car in front of me in slow traffic made a very sudden and complete stop.
I stepped on the brakes; after a second, as I slowed down, the brake feel completely changed and became harder, and I realized that I hadn't been alone - initially, car was braking for/with me, as confirmed with the massive orange letters on the dash board. Then as the system felt it was out of most immediate danger, it released and it was just me braking (that was the brake pedal feel change).
I do occasionally have it engage stage 1 of 3 (1 Visual -> 2 Audio -> 3 Auto Brake). It happens once a month predictable on very slight curves when it thinks I may be accelerating into oncoming traffic.

You don't actively engage AEB, at the kinds of low speeds involved AEB would have engaged and at least helped stop the car.
This was traffic that was going maybe 20 mph, and the car still hit me solidly enough for my car to lurch forward and almost hit the one in front of me

But as an aside, this is why Tesla's "Full Self Driving" shouldn't be on the market: It is always human error.
Even if FSD was enabled (I hope it wasn't) it'd be the human's fault for not reacting.
But it could also be a case of the person turned it off because of course Tesla let’s you control that.
IMO if the car thinks you’re going to crash it shouldn’t let you override AEB period. Why this isn’t a law…
Seriously?!? Tesla drivers learn to basically always have their foot on the accelerator, because the car slows quite aggressively with the accelerator all the way released.
IMO the one-foot model makes it quite hard to drive without lurching a bit and without unnecessary accidental light breaking while cruising. I often imagine that careful haptic feedback on the pedals could enable a much better one-pedal or blended braking experience.
That's pretty neat
My 2017 Lexus RX has high quality adaptive cruise control (radar based), super good parking sensors, 360 camera, rear cross traffic alert.
But you know what it doesn't have? Automatic parallel park. My friends fking Toyota PRIUS has automatic parallel park!
I used to parallel park in seconds, now it's an ordeal.
Life is difficult without backup camera tho.
They have run out of sensors, and they don't want to pause production until they have produced more.
Tesla doesn't operate the dealership model, which all tend to double up as a service station. So it's far more difficult for customers to get to the telsa service stations. Since there's less, that also means they'd be insane waits when the product comes back in.
This is the most basic feature that almost every car has had for years - but not your $60k Model Y. Why can't they wait to remove sensors until they've achieved feature parity with the vision only system? This seems crazy.
I don't really understand the push to do everything through the cameras. This has caused other problems too - like their decision to control automatic wipers with just the camera. Which meant in my Model 3, the automatic wipers were erratic and ineffective while in every other car with a normal $5 rain sensor the feature worked great.
