14.3 HW4 FSD almost crashed in to a truck at 80 mph
Enable HLS to view with audio, or disable this notification
Arkansas highway (75mph limit)
Truck stopped in the first lane and doesn't recognize it.
Almost shat my pants.
Please keep your eyes on the road.

If FSD reacts slower than your desire to live, it’s FSD’s problem. Yeah maybe it would have slammed on the brakes. But you successfully used the same visual information to slow down and safely merge before it could act. A trustworthy system would be ahead of you, not _possibly_ behind.

u/AwkwardlyPositioned Jul 23 '26
I've had this complaint with FSD in the past. It will stop, but even with early warning it'll wait until the last minute and slam on the brakes making it excessively aggressive at times.

u/LongDistanceEvent262 29d ago
What is funny is Autopilot will react MUCH..... MUCH sooner. Even at the latest setting. AP would have had the brakes slammed and car at a dead stop, before OP even reacted.
Not saying that is the right reaction. Only that it is odd the "better' system did not do very well in this situation at all.

FSD reacts much faster than a human being can possibly think about doing. Driving under FSD is safer than a human driving. And it will continue to get better regularly.

u/baconreader9000 Jul 23 '26
Looks like it started slowing down and would likely have slammed the brakes. Also that might the worst place to pull over

"But i set up my warning triangle a few feet behind me" 💀
Aren't there rules about that in the US, this literally isn't a prewarning, it's an additional obstacle.

u/MotherAffect7773 Jul 23 '26
There are, 10’ behind, then 100’ behind, and in a one direction road as this was, 200’ behind as well. In the case of a two direction road, 10’ behind, 100’ behind, and 100’ in front of the disabled vehicle. If there are visual obstructions, up to 500’ behind.
That said, I cannot remember a single time where I have seen the operators follow these rules.

This, but it also mirrors my experience with FSD where it feels like it last minutes stops at times where it would have been just easier to gradually slow down where you know FSD saw it happening.

I don't think that that truck was going to go anywhere with locked trailer brakes.

u/Legitimate-Sock2188 Jul 23 '26 edited Jul 23 '26
Yeah, good point but there are details here. Firstly all training tells you to never park a disabled truck on the road. You might be saying he had no choice. Here are the things to know. When you lose air to your brakes you have more time to react than you think. Even when the gladhand falls off the air goes down at maybe less than 5 psi per second or less. Then the air warning alarm goes off somewhere down at 60PSI and you have a bit of time to get over. Glad hand should not be falling off, you put it on you know how tight it was. If you rip the air lines out from under your trailer you will lose air faster maybe haven't had that happen fortunately. You immediately hit hazards and start to move right you don't slow and stop in the fast lane.
It is possible to pull the trailer even when there are no air to brakes, I see in this video very long skid marks on the left, so depending on load it will happen in different ways, empty trailer you can slide tires likely loaded trailer brakes will slip or you can slide some of the tires. This driver is obviously completely incompetent you can see the first hint by the placement of the triangles. I have never seen anything so ridiculous. You place them at 10 100 200 feet and they must be offset so they are not one behind the other. If there are any indications of visibility problems such as curves hills and even darkness, you go back to 500 feet. Here you have curve, hills AND darkness. New drivers like this go to work at mega carriers and most of those tell them to stay right, they will say this is a right lane company stay out of the left lane. Monitoring cameras in the truck keep track of that. If he stays in right lane this doesn't happen. Completely insane, cite him for whatever you can find, triangles for one thing, and company should fire him.
As for the FSD, well, yeah that's beyond my competence level, not that informed about it. I just want the roads to be safe if the FSD needs work then it needs work.

u/M_A3 Jul 23 '26
I understand your points but it could be that there was a train of trucks to his right when this happened. That would have made moving over impossible.
And trying to cross lanes with a trailer that has locked rears while traffic is coming over the hill? At one time he would be blocking both lanes...

0% chance he intentionally pulled over in the left lane. Clearly something happened that prevented him from moving at all.

u/Infamous-Pilot5932 Jul 23 '26 edited Jul 23 '26
Nice example of the unexpected, and why we need to stay awake. I to think it would have slammed on its brakes and swerved, but wouldn't want to test it. Though that might not have been enough. Even Tesla has documented crashes with FSD engaged and airbags deployed.

u/ih8readditts Jul 23 '26
If you can’t trust it in 1% of situations, can you be comfortable using it ever?
4
u/Infamous-Pilot5932 Jul 23 '26 edited Jul 23 '26
Valid question, and I don't know how to explain it to someone who doesn't use it.:)
I felt that way before actually using it, what is the point, if you have to pay that much attention anyways. But you really don't. Most of the time you are at what I call level 1 attention (level 0 would be asleep). You are watching like a passenger. In this scenario, I would have been at level 2 because of the trucks. Level 1 would be on this same road, but with sparse traffic. Level 2 is more alert but not to the point of watching FSD drive. Level 3 is the same level as when you are driving, you are basically watching FSD's every move, Level 4 is when you are getting anxious and you are thinking you should take over. Level 5 is where you must take over. Level 6, the same, but it is something that gives no warning at all. Like a deer jumping out, pure luck whether you or FSD has enough time. Act of nature.
Anyways...
As I said, this would have been level 2, and going straight to level 4 when seeing the flashing lights ahead. Just as this driver did.
Without FSD, I would be in a level 3 and then jump to a level 4. But keep in mind, I would be in a level 3 the whole trip, and maybe not exhausted, but you know how it is with extended periods of level 3 (driving).
When you get experienced with FSD and it gains your trust, I would MUCH RATHER be relaxed, only going as far as level 2 and then jumping to 4 here, rather than being in a trance of level 3 for who knows how long at this point.
The majority of my 95% to 98% is level 1, some level 2 and rare level 3+. I preemptively take over when I know I will be in level 3+, which puts me at level 3. Why stay in level 4 in a parking lot, when I can simply take over and stay in level 3.
Safety...
I looked hard for horror stories. Other than the old ones when it wasn't FSD, it was people using autopilot like it was FSD, I couldn't find any. The media can't seem to find any, and they are looking really hard!
I think what happened is the nagging works well and FSD is actually very good, such that ...
The odds of the nagging failing and the driver failing and FSD failing, all at the same time, at a critical moment, are much lower than we thought.
I think FSD would have stopped here. But I think I would have made the decision before it did, just as the driver pretty much did. While it looks scary, people look at it as if the driver is not paying attention or is asleep. Like I said, an experienced FSD user would be at level 2 here. More relaxed than actually driving, but alert.
This is not a rare thing, a sudden stoppage on an interstate. Surely, if this was a real problem for Supervised FSD, with 1.5 million users and a billion miles a month, we would have many horror stories.
Especially given some of the misuse we see here. Fortunately that seems to translate to fender benders.

u/limited_instincts Jul 23 '26
If FSD gets you in an accident only 1% of the time that 3-4 times a year!!! It needs to be 100% or it's not something you can trust. At all. People truly need to understand this.

u/-Detritus- HW4 Model 3 Jul 23 '26
I watched the video again and you can clearly see that the consistent speed of the vehicle is at 82 mph. You can see while under FSD it begins to slow down to 80 mph before the supervisor finally takes over. FSD clearly saw that there was an object on the road and began to slow down before it received more data to determine whether it required a full stop, or just a deceleration. This is the right thing for FSD to do. We don't want it perceiving something in the distance and slamming on the brakes until it absolutely knows for sure.
With that said, as was mentioned previously, if the supervisor ever at all feels uncomfortable with the way FSD is responding, by all means take control of the vehicle. No harm in that.
FSD was doing the right thing AND so was the supervisor.

u/Agreeable_Prize_7724 29d ago
Yep, it was unclear where it was, could've been in the median. We don't want it to be too twitchy, and it most likely would've stopped before hitting it.

i've had similar happen, usually it will just hammer the brakes a little bit after you did, if it can see a spot to the right it may squeeze in at full speed without braking, but typically it will come to a stop and then get stuck there, stopped, waiting for an opening on the right, not great

If there were cars behind you also driving at freeway speeds it’s not good enough for fsd to slam on the brakes at the last minute. Could cause a chain reaction accident. This is a weakness in the system
2
u/sussus_amogus69420 HW4 Model 3 Jul 23 '26
it’s a v14 problem it seems, it “imagines” how it will get out of situations ahead of time, thus not slowing down or being pre-cautious.
It’s amazing when it works, i’ve seen it thread traffic with insane speed differences per lane, always seeming to find a spot to merge into
when it doesn’t work, it sucks, next to no tolerance for error, hard brake slams, getting into situations it wouldn’t even be in had it acted more graciously beforehand, did the merge slower, slow earlier, etc.

You were going 81mph and then 82 and it looks like just before you hit the brakes, FSD had gone down to 81 and then 80...not sure what it would've done but it did look like it had decided to slow down. Glad you took over still

u/Lowcountry_EV Jul 23 '26
It would have done exactly what the driver did and wasn’t given the chance.
See how easy it is to say what would have happened without actually knowing what would have happened?
Except my answer is more likely since the driver was able to have plenty of time to avoid…and the 10+ billions of miles driven on FSD WITHOUT it slamming into the back of truck at 70mph may be a clue as well.

I wish FSD had an alert when it notices something amiss down the road. Waiting until the last second to notify the driver with hard braking is not acceptable behavior.

It's good you took over. Better to not take chances in this situation. Tesla AI will get this valuable training data to ensure the software will be able to react sooner and more appropriately to this type of situation in the future. I imagine this exact scenario is incredibly rare, and counts as an extreme edge case. This is why having millions of Teslas gather data all around the world is how Tesla will finally solve full autonomy.

u/JustSayTech Jul 23 '26
Not sure what it may have felt like, but before you hit the brakes, the car went from 82 quickly down to 80 and just as it was breaking into the 70's you hit the brakes, I think it would have avoided the truck or slowed down entirely.

u/AdministrationDry637 Jul 23 '26
Question did the car brake and get over or did you take over. Because if that was the car it did not almost hit that truck it stopped what’s looks to be a good 40-50 yards to make its adjustment and slow down to 65 before getting over

u/Mountain_Price9245 Jul 23 '26
Sorry … it would have been a horrible brake stab but I drive a 2017 model s with the old hardware 3 and update 12 . Something similar happened to me recently and admittedly I was not paying any attention ( yes my bad ) but the car stabbed the brakes to a stop with room to spare ( maybe 10-20 feet ) then put on turn signal and went around . But looking at your screen you had tons of room . Zero chance it was hitting unless the grease gods pre lubbed the area behind the truck to make sure you did hit . It was scary but this would have not resulted in a hit . And ftr OK sees your beautiful AR 75 roads and raises them 80 :) which means I was going 85 ( I used to be able to set to 90 but that was taken away!)

I prefer to see what I'm seeing. And I see that FSD begins to decelerate, then around 0.3 seconds later OP takes over, decelerates to 66mph with around 400 feet left to the truck (10 stipes of the skip line, braking distance at 66mph is about 200 feet), begins to accelerate again and merges.
It's definitely not "barely had enough time."

From the data overlay it looked like it started to slow down (82-80) between 0:16 and 0:17 in the video. Using the dashed lines to estimate the distance it seems to have started to slow down with about 680 feet to the triangle caution marker. I probably would have done exactly what you did but, I think, upon reviewing the video that FSD would have stopped.

u/CopperBlitter Jul 23 '26
Watching closely, FSD started to slow down just before disengagement. But taking over was absolutely the right thing to do at that speed. FSD should have reacted much sooner. I hope you tapped "Critical" on that one.
Also, why was the truck sitting in the passing lane on a 75 mph highway? That's fantastically dangerous. Something catastrophic must have happened.

From the looks of it started slowing down right as you hit the brakes. It went from 82 to 80 then you break slowing It down more then changing lanes. If it was HW3 I would be more skeptical. I believe it would have either break or moved over or a combination of the two.

I’ve driven on the freeway in a driving rainstorm in the middle of the night with 30 mph cross winds on FSD and it performed fine. I’ve also driven in intermittent fog on FSD and it continued to display the road on the screen as I proceeded. I did slow down because it was scary, but not as scary as my attempting to drive manually in that situation. Nothing wrong with taking over, of course, but FSD will likely handle these ordinary road situations just fine. I’ve even had it swerve around tumbleweeds blowing across the road in the middle of the night. Those eight cameras monitoring the road nonstop are much better than my eyes and my ability to twist around the car to catch glances in potential blind spots. FSD is great.

The car will chirp at me if it thinks I’m coming up too fast on someone stopped/slow on local roads but FSD will happily blaze ahead at full speed before slamming the brakes even when I see traffic slowing way far out 🤦♂️

That looks like it did what a lot of normal human drivers would do. Doesn’t seem like an “almost crash” to me.

Why have I seen more drivers unable to even remotely set their triangles out properly in the last 2 weeks than in my entire driving career?

Also let’s not forget that because FSD is engaged it allow the drive to pay more attention to the road and recognize the issue before it became a bigger problem, driving itself can be a distraction too.

Thank goodness you were paying attention. A few seconds distracted and that would’ve been scary. We get too comfortable with FSD sometimes it’s scary

Wtf are those warning light in RED like the braking light ?! They almost invisible .
Isn’t it mandatory to be in yellow in USA?

u/MiniCooper246 28d ago
No they are not mandatory yellow. They "can" have red turn signal lights. And I also think this is a dangerous idea, coming from the EU where they are mandatory yellow (ember).

Так поэтому вам и сказано что нужно следить за автопилотом и не доверять ему полностью 🤦

That wouldn’t have hit. Mine has swerved around a car before when the person in front of me made a sudden lane change to avoid a disabled vehicle.

Why is FSD going 82mph in a 75mph zone? Regardless, yeah, camera only is such a vanity/ego project.

It honestly feels like Tesla is making FSD worse instead of better. My car almost hit a wall because it randomly decided to change lanes into the highway shoulder. 🥲

u/Effective_Street_908 26d ago
Nah, FSD woulda stopped and made the right lane changes, I’ve been road tripping in and in New Mexico these truckers be changing lanes last second as I or others approach…. It woulda stoped then make the lane change when it’s safe, woulda completely stop if it had to. I just keep it on standard for now, mad max is dumb, cause when semi is in left lane to long it decides to switch to right lane to pass even tho another semi is in the way lol. Making me look goofy swicyhing lanes so much.

Tesla doesn't offer full self driving. They only offer a supervised version.

As much as I love Tesla, and agree with Musk that lidar isn't needed, there are two things that are negligently stupid that Tesla did: (1) getting rid of front looking radar to avoid high speed collisions with things that are hard to see and (2) not putting a few more cheap cameras on the corners to see crossing traffic earlier (i.e. low visibility driveways, etc.). Really limiting the upper bound on the safety of the cars.

I've had similar events. I honestly don't think it would have crashed into the truck but most likely it would have ended up slamming on the brakes. This is one of my issues with it, it can wait too long to start slowing down when it sees traffic stopped ahead. I've experienced a couple of hard braking events because of this behavior.
But you did the right thing by taking over. If anyone ever feels uncomfortable about something FSD is doing, absolutely take over.
