> I don't understand how something this broken is allowed to operate on public roads. It's important to point out that this software is currently only offered as a private beta to deliberately selected testers. Now, maybe they shouldn't be using it on public roads either, but at least it's not available to the general public.

Why not have redundant sensors and crosscheck them? Boeing 737 Max had only one AOA sensor [1], and that wasn't a great idea. https://www.cnn.com/2019/04/30/politics/boeing-sensor-737-ma...
Right, so what happens when one says wall, and one says clear air? You brake? That is what happens now with phantom braking. Approaching a bridge? camera sees air, radar sees wall, slam on brakes. You want the best sensor type over a high-fidelity sensor and a lower fidelity sensor. The Tesla system has 8 cameras (3 forward), so they def have overlap between what they are considering better cameras. Time will prove w…
> camera sees air, radar sees wall, slam on brakes
Seeing bridges as walls is not a fundamental property of radar. That's an implementation problem. If cars are doing radar poorly, maybe the fix is to start doing it less poorly instead of throwing it away entirely.

4 deaths is worth a 1% increased chance of achieving self driving a month earlier. Way more than 400 people a month die in car accidents.
I just don’t understand why people think a robot can improve on this. If you want to save lives, lower speed limits, build out public transit, and don’t hand out drivers licenses like candy.

FSD occasionally requesting driver to take over in genuinely difficult situations would be completely fine. The videos in the Twitter feed are nothing like that. The car makes potentially catastrophic blunders, like driving straight into a concrete pylon, with 100% confidence.
You know these are extract from multiple hours of video and it's a closed beta?

That's simplifying the situation a bit too much. The camera can give more results than air/not-air. Specifically in this case it could detect a bridge.
Same applies to the radar really - you'll get measurements from multiple heights which would tell you that it may be an inclined street, not a wall.

>The monorail video is jaw-dropping. Who needs radar right? A few cameras are enough to discern gray concrete structures in the night, oh wait ...
They probably would be if they stopped using such shitty cameras. It always blows my mind that the cameras they use appear to be quite bad for the job. > in the night Purpose-built cameras can see better in the dark than humans can.
And yet...

> ...doesn't matter how well it does in 90% of situations... Based on the full-length videos, I'd say it's more like 99.9% or even 99.99% for FSD 9.
The rate of driving fatalities is ~1 per 60 million miles driven. At an average speed of 60 mph that would be ~1 per million hours. Even if we were to assume there would be only one fatality-inducing error per hour, 99.99% success rate would make FSD 9 100x more dangerous than the average driver. I do not remember the exact numbers, but that would make FSD something like 1000x more dangerous than the classic example…
> In the 1st quarter [2021], we registered one accident for every 4.19 million miles driven in which drivers had Autopilot engaged. For those driving without Autopilot but with our active safety features, we registered one accident for every 2.05 million miles driven. For those driving without Autopilot and without our active safety features, we registered one accident for every 978 thousand miles driven. By comparison, NHTSA’s most recent data shows that in the United States there is an automobile crash every 484,000 miles.
Re: Scenarios in which Tesla FSD Beta 9.0 fails
#268Why are there so many comments from seemingly different posters all saying the same thing on this, "I don't understand why humans are allowed to drive cars"? It feels kinda... culty? Or too similar to be a coincidence. It honestly probably is but these Tesla posts always bring out those types and it confuses me. Humans kill humans, do we want machines to start doing it on the road automatically now too?

Here's what happened another time someone argued that "radar can't detect stationary objects". https://news.ycombinator.com/item?id=16722461 Radar does detect stationary objects, come on.
Yes, radar can easily detect stationary objects. Tesla's implementation of their radar processing drops all returns from anything stationary, given the forward speed of the car. In the context of a Tesla thread, I didn't think that needed to be specifically stated, but will do so in the future.

> I don't understand how something this broken is allowed to operate on public roads. Also out in a rural area. Running out to pickup lunch a few minutes ago, a young man flipped their old pickup truck on its side in an intersection, having hit the median for some reason. I too don't understand how humans are allowed to operate on public roads. Most of them are terrible at it. About 35k people a year die in motor veh…
