Polestar crash

[LoPro]

A Polestar on “driving assistance” swirled and crashed in a road lamp in my town today. Refreshing that “FSD crash” news are not all Tesla with big letters anymore. Of course they only called it EV instead.

I hope they have good logs.

I am not sure about Polestar but it makes me wonder how a Tesla FSD that works based on vision/light alone deals with shadows. In a time of the day like this and sky like this as clouds move in and out, horizontal shadows keep appearing and disappearing. There must be a contrast threshold that FSD uses to decide if the shadow is an object or not. I never gave this stuff any thoughts before but it is fascinating. If any of you have worked on the stuff feel free to dumb it down for me and break it down to it’s pieces (how computer vision works in this context).

Yeah, if you think about it, object permanence is a hard problem.

...how a Tesla FSD that works based on vision/light alone deals with shadows.

I would just like to point out that every automobile control system on the road now (with extremely few exceptions) works on vision/light alone.


<To be clear, I’m talking about humans>.

Gives you new respect to the pattern recognition monster we carry around in our skull.

This one shouldn't be even a news. Only Tesla crashes should be reported and investigated.

I hope the FSD software has this already accounted for especially during the mornings and evenings when the shadows are the longest. With enough evidence (as in millions of repetitive data), I don't see this as a big problem that they cannot overcome.

Simple..... FSD is smarter than people.....it doesn't have emotions....its not in a rush..... it decides based on empirical facts.

lol no doubt..... some short seller will try that angle.

I wouldn't say smarter...

But it should be possible for the training and testing datasets to exceed the total amount of experience a human driver could possibly gain in their lifetime.

It's possible that, in the future, a fully mature FSD will be more experienced than any human driver alive.

That would be so cool!

I'm sure there will be a press release about it when they get there.

I did some Googling on shadow detection and many interesting projects have already been done for other applications. Really cool stuff. I think, if there are unresolved cases, they will go on the side of caution so your CT will slam on the break when there is nothing there as opposed to running over someone’s kid assuming it was a shadow. I didn’t order the FSD but I am still fascinate.

Really, we just keep learning how much more there is to learn.

And often, no one wants to actually pay for the AI. Not while humans are cheap (and given inflation, cheaper).

Humans biggest driving problem is low sun ahead (or so I was told I’m driving school), and that’s a problem in all northern regions during the winter.

I’ve tried autopilot while staying vigilant while driving through many short tunnels and under bypasses with the low sun in my eyes (on the way to the cabin, I haven’t been in the office for over a year because of a certain pandemic and our country’s little leverage in getting vaccines (when the shit hits the fan it doesn’t matter how rich you are)). Amazingly autopilot still manages it in about 99% of the time (not counting when heavy snow on the highway). At just the right angles and times it freaks out or slams the breaks though.

Then there’s fully grey low contrast days and I also get brake slams, but at other places under bridges and towards tunnels.

With just vision I can’t imagine how fsd would be able to get this better than us and work 100% of the time. But smart people are working on it.

Lidar is also blinded at those times.

I think it would be Tesla's plan here to leverage the cameras against each other in their all-in-one composite view for the AI. So the AI can do the human equivalent of squinting out of one eye, but with seven others.
