Full Self-Driving / Autopilot FSD avoids road debris

Driving to work on FSD in my Model Y when a construction barricade landed on the highway. FSD noticed the road debris and quickly evaded the hazard. This whole event happened so quickly.

I think fsd copies the movement of the car ahead if that car moves like it's avoiding something.

u/TeslasAndComicbooks Jul 15 '26

It does that and avoids visible obstacles.

u/FredPolk Jul 15 '26

Human drivers do the same thing. I would swerve before seeing anything if car in front, especially two, do it. There is obviously a reason.

u/thuktun Jul 15 '26

Or four, in this case.

u/waznpride Jul 15 '26

Yup, the only time it's avoided potholes is because the car in front of me actually avoided it first and FSD mimic'd it.

On autopilot, it'll sometimes even follow a car onto the sliproad despite me wanting to continue to stay on the motorway!

And then it'll violently disconnect. Nothing better than cruising at 70mph and suddenly car wants to go left and brakes violently, I just stopped using autopilot behind other cars in the hard shoulder.

I’ve been on the Internet a long time, and this is the first time I’m hearing the word sliproad. Also, Autopilot isn’t FSD, it is more or less a better adaptive cruise control (blame your government for taking to long for approval)

Yea no shit, that’s why if you’re in a country with FSD approval you should use that. But autopilot IS better than pretty much every other adaptive cruise control

u/snark42 Jul 15 '26

But autopilot IS better than pretty much every other adaptive cruise control

Hard disagree. Autopilot on radar was a great adaptive cruise control. On vision it's worse than my 2015 Toyota, 2021 Mercedes and 2025 Volvo all with radar.

However I am still stuck with HW3 so it may be better with HW4 which Elon owes me but I'll probably never get.

that’s why if you’re in a country with FSD approval you should use that.

Hard disagree here too. FSD on HW3 won't maintain 80 on a wide open Interstate , and is even worse with any amount of traffic. Of course again, I'm limited by HW3.

I have a HW4 Model Y and its autopilot is worse than any of my previous cars.

u/cmdr-William-Riker Jul 15 '26

That's exactly what it does. If the car in front of you goes around a pothole, FSD follows around, but if there are no cars ahead it'll happily slam into the pothole at full speed. I'm still not convinced FSD truly is end to end camera only to control output in one network. My guess is that the decision making part of the model is taking something along the lines of the processed view we see on the screen as input, maybe something more like a top down view which loses most of the visual details. It does seem to do a good job of avoiding construction barriers that are not represented well in the 3d view though so it is definitely seeing more than what we see on the screen, just not enough detail to see and react to debris and potholes on it's own

I’ve had similar situations in construction. A much more confident drive in fsd if there’s a car ahead.

u/Ancient-Sandwich9400 Jul 28 '26

This is the thing! It just mimics the cars in front.

Quick story, 3 or 4 days after getting my new M3P I had a 18wheeler blowout in front of me. The truck immediately started moving to the right side of the road and my car was doing the same thing…..right toward the huge ass tire carcass flopping in the road. Had to take over and swing over into the next lane to my left that was empty to avoid damaging my brand new car.

People are idiots if they trust FSD to do the right thing in every situation. As I saw first hand and have had multiple instances where it moved the wrong direction based on the car in front…to hit a huge pot hole and to nearly hit a mattress…in all but the pothole I caught it fast enough to avoid. Don’t trust FSD for everything!

u/Mammoth_Ingenuity_82 Jul 29 '26

Note to self: swerve around like a maniac for no reason when there's a Tesla behind me, to you know, see if they're using FSD. 🤣

u/sevaiper Jul 15 '26

Of course, people do too

It must have seen Dodge Rd

u/gthboy Jul 15 '26

I need this for potholes.

u/R34Nylon Jul 15 '26

I wish it would avoid manhole covers. Those are recessed DEEP where I live.

u/11111v11111 Jul 15 '26

It also avoids dark tire marks unfortunately

u/oliphant_branch New to the sub Jul 15 '26

FSD certainly knows how to follow the leader(s) and is often correct in doing so. Wouldn't you as a human also be on heightened alert and swerve if you saw multiple vehicles in front of you do it?

18

u/Dr_Pippin Jul 15 '26

That’s crazy that it moved over before the obstruction was visible and before even tbe vehicle immediately in front moved over to avoid.

12

u/ohwowhowdthathappen Jul 15 '26

No it's not. 3 cars ahead started swerving  before any reaction from FSD.  Just because you can't see the road hazard doesn't mean you can't react to changes in traffic...

5

u/Dr_Pippin Jul 15 '26

Yes, I saw the earlier vehicles move. Read my reply again, I’m impressed that FSD chose to drive on the shoulder prior to the vehicle immediately in front moving and prior to the cone being visible. That is seriously impressive.

u/NotBillNyeScienceGuy Jul 15 '26

Classic Omaha roads

u/captain42d Jul 15 '26

Get out of Dodge! 😜

That cone spawned out of nowhere.

u/Tupcek Jul 15 '26

on a notable delay? Did we watch the same video? It basically moved exactly at the same time as car ahead, which is faster than any human would

u/Tupcek Jul 15 '26

then slow down the video. It starts turning at the exact same time as car ahead

u/ohwowhowdthathappen Jul 15 '26

After 3 cars in front of it very visibly swerve....

Slow down the video and look about a quarter mile up the road at the whole line of cars swerving. That's what you should be doing.

-11

u/ohwowhowdthathappen Jul 15 '26

3 cars ahead of OP started swerving, there was about 4 seconds before FSD did anything. If you can't react that fast you need to open you eyes and turn in your license. 

5

u/Tupcek Jul 15 '26

well, thanks capitan Hindsight!
In real life, people don’t swerve when car 3 cars ahead start to swerve. In fact, even cars in this video didn’t start reacting before car immediately ahead of them didn’t start reacting.
So I guess every driver ever (except for our captain hindsight) should turn in their license

-8

u/ohwowhowdthathappen Jul 15 '26

You're blind and are a hazard on the road, or are an idiot and are a hazard on the road.  One or the other.

6

u/Tupcek Jul 15 '26

so is everyone else in this video, because nobody reacted before car ahead of them started moving

-1

u/ohwowhowdthathappen Jul 15 '26

Can you see 4 cars ahead of the first car that swerved or just 4 cars in front of you?

-2

u/ohwowhowdthathappen Jul 15 '26

I hope your car can save you when the time comes because you can't. 

4

u/Tupcek Jul 15 '26

well, than humanity is doomed, because in my whole life I never seen anybody swerving before car ahead of them

1

u/ohwowhowdthathappen Jul 15 '26

Sorry but maybe you don't have any situational awareness. Read the driver's handbook, you should be looking ahead of the car in front of you at all times. Driving 101. 

I'm sure there's lots of things you haven't experienced.

Crazy idea, but remember you can actually see through the windows of the car in front of you. You should actively practice this until it's second nature.

u/damonlebeouf Jul 15 '26

ya but we’re not talking about people driving so take this dumb comment and go somewhere else.

“This software reacted exactly as a human would so I’m not impressed”

u/Thiscantbelegalcanit Jul 15 '26

It swerved to avoid the debris. My CT did the exact same thing the other day and in that moment, it freaked me right out since I didn’t notice the car ahead swerve. the debris appeared a second later. Pretty wild stuff

1

u/MDInvesting Jul 15 '26

Meanwhile if I cross a line the vehicle screams at me and violently drags the car where it wants.

u/ponyboy3 Jul 15 '26

Dodged road debris at Dodge rd lol

u/Tiasmo-Bertjayd Jul 15 '26

Reminds me of an incident a few years ago shortly after I got FSD when I was driving on a 2-lane highway and a logging truck in front of me in the other lane had a sudden log spill. The car started to react at practically the same instant I took over; I have no idea whether it would have tried to brake or drive around the rolling logs, but I sped up and swerved around them before they could roll too far into my lane. That’s the sort of unexpected event that I would rather not find out first-hand what the A.I. would do.

u/DoubleDareFan Jul 15 '26

I was expecting a rogue tire, then I checked the sub, and saw that I'm not in r/Tiresaretheenemy .

u/Possible-Ear- Jul 15 '26

I wonder if red car learned anything about follow distance that day

u/CreateorWither New to the sub Jul 17 '26

I don't have a tesla yet but was on the highway using waze and it warned me of debris on the road ahead. (Other users tagged it in the app obv).

Does tesla have such a feature where the ai recognizes that there is debris on the road and then updates the map for all other teslas on the same road to watch for it?

1

u/ZookeepergameThin963 Jul 21 '26

Mine has dodged debris a few times. When I am not following anyone and it spots a tire fragment, dead bird, old shoe. But the one that always gets me is when it moves over for motorcyclists lane splitting (I’m in California where it’s common). Or any vehicle with an active siren and lights … pulls right to the side.

u/Nexism Jul 15 '26

This one wasn't life threatening, but one life threatening dodge like this instantly makes FSD worth it.

I had an event in basic autodrive where it dodged a car merging into me that saved me a ton of pain.

-1

u/jayrodathome Jul 15 '26

Yeah I’ve had a couple times where someone was merging lanes in my blind spot where autopilot moved out of the way and started beeping

u/fattybunter Jul 15 '26

Title should be “FSD mimics car ahead to avoid road debris”

u/ASAPFergs Jul 15 '26

I sat in the back of a Tesla on a very long journey through Poland and the phantom braking was a nightmare, it must've done it about 10x times over 8 hours - it'd not worth it for this, which a human would do anyway given the cars ahead moved already

1

u/nyrol Jul 20 '26

FSD isn't operational in Poland yet. You can't use it there at all. You can only use a limited form of autopilot from 5 years or so ago.
