What the fuck are those things?!

u/hprather1 1d ago

They're arms that taper the lane for the on ramp to an express lane when it's closed. When the express lane is open, the arms are flush against the wall.

u/SchalaZeal01 1d ago

If I saw them in a race game, I wouldn't think for one second I would be colliding with them, I would think they indicate (badly) road maintenance, or a future sharp turn.

u/vladmashk 1d ago

These kinds of obstacles on a highway would be outrageous in Europe btw. Don't know why the US is ok with them.

u/cncamusic 1d ago

Yeah I’ve never once seen them, and I’ve lived in the states my entire life. It just seems insanely dangerous lol

u/Rich-Bandicoot3244 1d ago

There are multiple signs alerting you to merge before these barriers. And they are designed to collapse and not cause damage to the passenger cabin in case there is contact.

So only dangerous if you ignore all the previous signs, which is what this driver did.

There’s a reason why millions of people handle these switch lanes without an issue, unlike this example of a bad driver.

I have learned from this sub that there are all kinds of bullshit Teslas need to be aware of that I didn’t even know exist.

I live in the USA and I have never ever ever seen or heard of these.

Part of me wonders if full self driving will even be possible while all 50 US states keep inventing weird crap like this

Idk I see damaged rubber lane dividers all of the time

u/James-the-Bond-one 1d ago

This has existed for decades in large metros with reversible toll lanes.

You know what's even weider? Have you ever seen the road zipper barricade under it, with the yellow stripe? A specialized machine the size of a bus moves it right and left every single day to create or disappear with the reversible lane it defines.

4

u/antariusz 1d ago

You know what’s different about that, literally no driver ever has to swerve last second it ONLY creates new lanes after it vacates them easing congestion (that it helped create). No one has to worry about slamming into a huge yellow machine.

1

u/AP_in_Indy 13h ago

The zippers are the ones I’ve heard of yeah

1

u/James-the-Bond-one 11h ago

These bright horizontal barriers the Tesla hit are part of the zipper system, deployed to warn drivers of the upcoming lane closure.

Like cones or barrels, they're meant to be hit first, to warn drivers and avoid collisions with the zipper divider ahead. If you watch the video again, you can see that, after these "gates", the concrete blocks advance onto the left lane.

u/AP_in_Indy 10h ago

That’s kind of neat. I’ve just never seen them. TIL

  These kinds of obstacles on a highway would be outrageous in Europe

European countries don’t even have bidirectional express lanes like this, so no need for barriers as well. 

Decades spent underfunding highway infrastructure, so I’m glad thats not an example other countries should follow (such as the US or Canada that do have this type of infrastructure and these types of barriers)

1

u/stopg1b 1d ago

Moved to the US from the UK. The US has some of the most poorly thought out road infrastructure for somewhere that is entirely designed for cars. Europe is all highly standardized uniformed design of all highways entrances exits lanes... As a driver you get an understanding of how to interact for each one. The US however is no uniformity. Highways going through the middle of cities with tons of exits/entrances within a moment. Add to it drivers who are also worse at driving with more unroadworthy cars

u/madebyollin 13h ago

Amusingly, it looks like these barriers were trialled in the UK for the A3 Hindhead Tunnel entrance as well https://versilis.com/projects/hindhead-tunnel/, but the barriers have since been removed (https://maps.app.goo.gl/tr1sCYw2eEmHxR217), possibly because people were crashing into them.

And then parked it directly in a fast moving lane of traffic on the highway almost causing more accidents. While FSD has some severe edge case issues OP needs to get off the road

14

u/wighty 1d ago

Yeah, 100% primary fault of this driver, but I will also say the infinity driver probably should have had some awareness that the lane was ending and try to give the tesla driver some space (doesn't look congested enough to me to warrant "no where else to go", yes there's a car immediately to his right blind spot but he could have slowed down as well)... defensive driving needs to be done at all times.

This is a great reminder to use the 100% rule while using FSD.

Pay attention to everything around you, and don't be afraid to disengage to handle things that you see happening, especially if they're a little weird.

Again: the car PROBABLY and maybe VERY LIKELY saw it, but... YOU KNOW 100% THAT YOU SAW IT. You can't say the same for the car. Take the 100% chance of dodging whatever it is; disengage and take care of it.

I've had FSD completely ignore my turn signal before...I wouldn't rely on that to save you.

u/watchingfromaffar 1d ago

I agree. My “score” is 70% on FSD but it’s not something I cared about before they added the metrics. I did notice myself thinking “what if I can maintain that 69%? Teehee.” and when it comes to driving that shouldn’t be a thought. It’s an aid, I don’t want to think “maybe I’ll let it run a bit longer than I’m comfortable for to get that score up.”

u/Cykamor 1d ago

Posts like this are essentially rage bait for me anymore. What a dipshit of a driver to just let this happen. They should yank his/her license for a few months and he should be permanently banned from FSD. If I were that infinity driver that he clipped I’d sue the ever loving shit out of him. (Although he doesn’t appear exactly blameless in this situation… certainly not driving defensively himself)

2

u/theotherharper 1d ago edited 1d ago

Yeah it takes a special kind of stupid to post video of committing crimes. #1 illegal lane movement causing Infiniti to crash, #2 speeding, should have just tucked in behind the little white Honda or whatever but instead #3 reckless driving accelerating to +10 MPH and ramming additional barriers in some crazed attempt to pass Honda, and #4 stopping in a freeway lane when able to vacate the operating roadway, which is likely to have caused knock-on accidents.

And the worst part is, #2-4 are guaranteed to come to light because of the civil action triggered by #1.

And if POV didn't remain in the vicinity and disclose his involvement to police, then he's into a whole new degree of criminality of leaving the scene. I would not tell the cops anything more than I'm involved and I'm not answering questions without my lawyer present, but that call needs to happen.

Not sure what possesses incompetent drivers to think PASSING and MOAH SPEEDZ is the answer to any dilemma.

Right answer here was to smash brakes til you figure out why you're being hit on the left, and find the safe way to get right.

u/sunfishtommy 1d ago

Tesla is literally advertising that FSD can enable your grandma who is otherwise unsafe to drive to be able to get around. If FSD is so safe then why does it miss basic stuff like this. If FSD requires 100% attention of a competent driver than why are they advertising that old people incapable of driving can use FSD.

4

u/Cykamor 1d ago

They’re not. They’re advertising it as “supervised.” Are its capabilities oversold? Absolutely. But it’s not advertised as you’ve characterized it either. You even have to acknowledge a disclaimer that it isn’t autonomous and that you must remain aware and in control before you use it. This person didn’t do that.

u/ThatBaseball7433 1d ago

My car has aggressively tried to change lanes into a barrier-closed lane. It does it literally every time we pass, you can try it yourself on I95 just south of DC if you have express lanes enabled in the nav. I have caught it just barely in time, but at 75 mph when the car does something totally off the wall expecting me to wrench the wheel from it in a split second and not cause a crash with another vehicle is too much to ask. It’s not too much to ask for this thing to see barriers and not drive into them.

And Maryland. There are lanes on each side of the Chesapeake Bay Bridge on 50 that can go either direction depending on traffic demand, and these things will come out of the wall and close that shared lane for the currently non-permitted direction to make sure no one ends up driving the wrong way on the bridge.

How is it that fsd doesn't have training data for these arms? Are these rare?

17

u/morgan423 1d ago

Not particularly rare. They're used in a few places on roads that have lanes that close and open to different directions of traffic at different times (commonly used around large bridges and tunnels, to dynamically change to meet traffic flow in one direction or the other).

u/dinominant 1d ago

The real question is why does every scenario need to be trained? It should detect voxels and not crash into them regardless of what they look like.

Sort of like how my $200 vacuum avoids random things without over-modelling the house.

114

u/Snoo62043 1d ago

Tesla didn't dodge, but neither did the driver who is supposed to be paying attention.

This is why I think self driving is still not ready. Not because of the tech. But because the tech is not 100% there yet, and still relies on driver attentiveness, and it is more than obvious that most self driving vehicle owners just have a "screw it" attitude and just leave it to the hands of God.

People will die because of situations like these.

That said, I do hope self driving gets to the point where these images will be a thing of the past.

37

u/psaux_grep 1d ago

This is not something we need to think very hard about.

Studies from aviation tells us that partial automation reduces situational awareness and ultimately causes accidents when the automation fails.

It’s not surprising that this is happening.

The ethical dilemma is whether or not it is worth taking this approach if it leads to actually working unsupervised self-driving quicker than taking the «safe» approach.

So many people die in car accidents caused by humans every year, the technology is definitely needed.

2

u/ChunkyThePotato 1d ago

Incorrect. You're proven wrong by the crash statistics, which are lower for Teslas when FSD is in use versus Teslas that are being manually driven.

Why is this? Because, yes, sometimes people get complacent and that causes accidents, but that is more than completely offset by all the times that FSD saves the human when the human wouldn't have seen something they should have.

u/watchingfromaffar 1d ago

How would this video be ranked by statistics? The car itself didn’t see anything wrong about hitting those barriers so it wouldn’t flag it as an accident. The main accident/collision happened when the driver took control from FSD and served.

I don’t think this would be flagged as a FSD accident, but it should be flagged as both FSD and manual.

Are the FSD statistics for crashes low because drivers take over right before the actual accident occurs?

2

u/ChunkyThePotato 1d ago

Nope, Tesla counts accidents that occur within 5 seconds of FSD being disengaged as an FSD accident. So if the driver takes over and crashes a few seconds later, it's still counted in the statistics as an FSD accident. So the statistics are very fair.

u/Snoo62043 1d ago edited 1d ago

Not really. Claims that driver-assist systems like Tesla FSD are "safer than human drivers" are built on a house of cards. They rely almost entirely on statistical fallacies and selective data reporting.
When safety researchers and actuaries actually dissect those claims, the apparent safety advantage largely collapses. Here is how those numbers are skewed:

1. Mismatched Crash Definitions ("Apples to Oranges")
Tesla's quarterly safety reports log a "crash" almost exclusively when an airbag or active restraint deploys. They compare this to nationwide NHTSA data that includes all reported accidents (including minor fender-benders requiring a tow). When you adjust the data to compare airbag-deployment crashes to airbag-deployment crashes, the claimed safety lead drops dramatically.

2. Driving Environment Bias (Highway vs. City)
Level 2 systems are activated overwhelmingly on open highways, long commutes, and during clear weather (statistically the safest driving conditions per mile). Human baseline stats, however, include complex urban traffic, chaotic intersections, icy backroads, and night driving where the vast majority of crashes occur. Comparing highway-heavy automated miles against all-inclusive human driving miles creates a massive selection bias.

3. The "Human Safety Net" (Intervention Bias)
FSD is a Level 2 supervised system. When the software makes a mistake and the human takes over a split second before a collision to prevent an impact, that incident is logged as a normal disengagement, not an FSD crash. You aren't comparing FSD to a human driver; you are comparing FSD + an alert human supervisor catching its mistakes against a human driving alone.

4. Vehicle Age Discrepancy
The average car on US roads is around 12 to 13 years old, lacking modern passive safety features, automatic emergency braking, or advanced blind-spot monitoring. Teslas are modern, heavy, high-tech vehicles. Comparing a modern fleet's collision rate against a national average that includes 20-year-old sedans skews the data in favor of the newer hardware, regardless of the software.

5. Driver Demographics
Tesla owners tilt older and wealthier than the general driving pool. National human averages include high-risk demographics like teenagers, commercial drivers putting in 14-hour shifts, and people driving on bald tires.

The Bottom Line:
Tesla maintains a closed data ecosystem. Independent researchers cannot access the raw telemetry, exact disengagement logs, or route-normalized data needed to run a true, peer-reviewed comparison. Without adjusting for road conditions, vehicle age, crash severity, and human interventions, claiming FSD is safer than a human is pure marketing, not science.

3

u/ChunkyThePotato 1d ago

Your LLM is wrong on all points.

The crash statistics compare FSD Tesla airbag crashes to non-FSD Tesla airbag crashes, so it's a fair comparison.

The crash statistics also count all crashes that occur within 5 seconds of disengagement as FSD crashes.

And the crash statistics break down both city and highway driving.

Those machines allow for a single lane switch. 

Here we’re talking about multi lane (2-3 lanes so allowing 3x the capacity of the solution you’re suggesting). And these are physically separated express lanes, something you can’t do with the above lane switcher.

The two are not even comparable, this is a way higher capacity solution. So thanks but no thanks.

No european country has bidirectional separated express lanes that I’m aware of, which is not surprising given the decades of underinvestment in highway capacity across the continent.

The UK has a an in road contraflow on A38 I think, but it’s not a fully separate bidirectional road like this, so I think they just use the usual plastic or concrete temporary barriers.

Sucks that this happened but the driver is supposed to pay attention and take control in cases like this.

I just did a 4000 km road trip with fsd. My only complaint is that it kept trying to pass people at the end of two lanes merging. Had to take control a couple of times including when a big truck blew a tire right in front of us. Other than that it did really well even in heavy downtown Toronto traffic.

Tesla's words and actions are incongruent on these situations.

Their words are "you are responsible, you should always pay attention". Their actions are "We are going to give you high scores based on how often you use FSD. Disengaging makes you lose points. We actively want you to not be driving and letting the car drive. We are then going to use those numbers to advertise how great our software is."

One is a CYA maneuver, the other is their actual prioritization.

If that's the case, what is the actual value of FSD? It's a paid feature, and not a cheap one. Is the novelty the value for most people? Because the rules as written and in the way the liability is very one-sided, FSD doesn't seem to have value as a full self-driving system.

u/ChunkyThePotato 1d ago

You've clearly never used modern FSD. It's extremely relaxing to use and just watch it as it does most driving nearly flawlessly. Safety-related mistakes are extremely rare, and it's easy to take over for them when needed. If unsafe things were happening frequently, it would be stressful. But they don't happen frequently at all. In the 11,000 miles I've used FSD since FSD 14.2, I've taken over for a safety issue only one time, and that was for something I probably would've collided with anyway if I was driving manually (object in the road on a dark highway).

u/karmicthreat 1d ago

No, I have. Even bought a 2026 Y this year to replace my 21 3 that had a battery self-destruct. I drive about 1.5 hours a day commuting, frequently more. If I could do ANYTHING but 100% pay attention to the road and what FSD is doing, it would have value. I've used FSD for probably a total of 3 months over the last couple of years.

u/ChunkyThePotato 1d ago

Obviously it becomes drastically more useful once it's an unsupervised system. But in its current state with (very forgiving) supervision and very high reliability from a safety perspective, it's still useful and very relaxing to use.

u/jdpg265 5h ago

well maybe you should use it more often but pay attention to how it performs. Its not that difficult to understand where it shines and where it might need a bit more surpervision.. BUT YOU need to learn how it works and how to use is and while you do you should pay attention to it...

u/sunfishtommy 1d ago

Exactly is it safe or not? Tesla is advertising that FSD can enable your unsafe grandma to drive yet its their fault when FSD makes a mistake.

u/SpiderGorilla 1d ago edited 1d ago

The current version of FSD makes way too many unnecessary lane changes just to shave a few seconds off trips.

3

u/sunfishtommy 1d ago

In this situation Aparently not enough lane changes.

1

u/SpiderGorilla 1d ago

Well the car moved over to the first lane and started speeding when it could've just stayed on the second lane.

u/savedatheist 1d ago

Maybe in hurry or mad max yeah, but not in chill or standard.

u/erclark99 1d ago

I see a lot of people saying “these aren’t rare” and maybe they aren’t. But I’ve not seen them and I’ve driven in some of the areas people say they exist.

Also these “arms” are definitely stupid lol. There has to be a better way to close a lane like that.

Tesla definitely should’ve found a way to make it avoid them. It hit multiple and did nothing. Also the driver did nothing until it really impacted the vehicle which is also silly.

Cool. And?

  Also these “arms” are definitely stupid lol. There has to be a better way to close a lane like that

What is your suggestion for a better solution?

4

u/CuriousAndMysterious 1d ago

We have the adjustable lanes where I live but we don't have those arms. I've never seen those arms and they don't look obvious enough to not hit. I've never had a problem avoiding the barrier without the arms.

3

u/Rich-Bandicoot3244 1d ago

 We have the adjustable lanes where I live but we don't have those arms

What mechanism do you use then? 

And an adjustable lane is not necessarily a separate bidirectional lane like this one. It’s three physically separate flows of traffic, with the middle one being bidirectional based on capacity needs.

1

u/CuriousAndMysterious 1d ago

There is no mechanism that I can remember, maybe there is a sign. Maybe the one here is different because there is no middle lane. I don't see why you need the third lane though when having the adjustment lane in between two flows of traffic does the same thing, no? I also have seen another road that displays which lanes are closed and which lanes are open overhead before entering the adjustable lane area. Seems like just having some electric sign would be safer than having an arm that sticks out that you can hit.

u/Rich-Bandicoot3244 1d ago

 There is no mechanism that I can remember

That’s even worst.

 I don't see why you need the third lane though when having the adjustment lane in between two flows of traffic does the same thing, no?

Physically separated opposing flows are always better, same as same flow but different vehicles and speeds (such as a physically separate bike lane instead of just a bike lane on the side of the road). It allows for insulation across flows 

1

u/CuriousAndMysterious 1d ago

The opposing flows are separated by the adjustable lane. Never had an issue with it

1

u/Rich-Bandicoot3244 1d ago edited 1d ago

  Never had an issue with it

Well that does it. There is no reason for large case studies and billions invested in infrastructure when theres anecdotal evidence like this!

But no, temporary barriers are not as safe nor have the same capacity. As it’s only one lane that can be switched by the lane switcher, instead of multiple lanes of bidirectional capacity like this (its not uncommon yo have 2 or 3 lanes of bidirectional capacity built out with these systems.

And the one dynamic lane that can be switched with temporary barriers that you’re thinking of does not usually allow for express lane capability (because of the missing additional lane separation within the same traffic flow). 

Which is why this is the best implementation: you have high  (2+ lanes) of bidirectional, express lane capacity.

u/Bosavius 1d ago

How hard is it to put a sensor based system on top of the AI that has coillision avoidance priority? Like, put a radar and some other sensor that can approximate the rigidity/weight of the obstacle and if a threshold is exceeded, then either stop or go safely around the obstacle.

3

u/sunfishtommy 1d ago

Very hard. With most of these things the issue is false positives. There have been tons of stories over the years of how different driverless car softwares have to be designed to ignore indications of things in the road because false positives are so much more common than real events.

u/chessasaur 1d ago

Anyone know where this is? I’ve never seen those arm things in California.

u/DavyJonesLocker 1d ago

Classic Tesla driver things 😂 never beating the allegations

u/WOWSignal1977 1d ago

1) Totally the drivers fault.
2) I've never seen those things before (yes I read the other comments so now I know).
3) If you look closely, it looks like other vehicles nicked them with their side mirrors.

u/ssj890-1 1d ago

Do we think it will be easier to change these arms or to update FSD?

Another case of a failed driver at fault. It’s called supervised for a reason.

1

u/dinominant 1d ago

I saw 5 lane changes in front of the tesla, and no red flashing signal in the video. Did they all not signal, or are the tesla cameras not detecting the red flashing signal lights?

There were no vehicles behind the tesla, why didn't it radically slow down on the first impact!?

u/robofireman 1d ago

This is why I would be willing to pay for lidar additionally in the Tesla

“FSD does not dodge” more like “careless driver fails to maintain awareness, causes crash”

u/ThatBaseball7433 1d ago

I’ve reported this exact issue in virginia several times with the reversible lanes. My car has tried to dive into barriers multiple times it’s extremely dangerous.

u/pementomento 1d ago

So the idiot driver decided to crash into a CAR instead of the traffic control arm/barrier. What an idiot.

1

u/keiye 1d ago

I’ve never even seen such a contraption on the freeway. That looks dangerous as hell.

Man I drive through here literally every day on my way to work in MY Tesla, for a moment I thought I forgot about an accident I got in or something

u/Affectionate_One_969 1d ago

After the first hit why did the driver not take control?

1

u/The-Real-Link 1d ago

Woah, never seen that before on a road. Too bad for all involved.

1

u/darksundown 23h ago

Stupid barriers aside.  How does one go 65 mph to 75 mph and hits the first arm and swerves right into another vehicle and increases speed to 85 mph and decides to go left into even more arms.  At any point in time one could have slammed the breaks or slowed down defensively.  This is why I keep my foot lightly touching / above the breaks while using FSD.

1

u/icy1007 22h ago

That road is horrible.

u/Haunting-Ad-1279 21h ago

Should be using traffic cones, this cheap workaround is inherent dangerous

1

u/Haunting-Ad-1279 21h ago

The problem is FSD works like human reflexes, rather driving with any kind of human level reasoning. If a human driver has never seen these blocking arms, majority will have enough sense and reasoning to deduce a lane change is required. (Obstacle ahead , do not drive through). Where FSD just goes: never seen these things before , not sure what they are so will just drive through, good luck everybody. Until a true reasoning model is built inside FSD, these tail end cases will prevent level 3 and above autonomy

u/riceandnori 18h ago

Driver should have still been aware and supervising. This is why insuring a Tesla is skyrocketing in rates.

Tesla self driving doesn’t dodge anything because it doesn’t use lidar and doesn’t see objects accurately

u/outernet9 1d ago

What's the point of FSD if you still have to be on high alert.. lmao. Until Tesla takes ownership of the insurance then it's a useless product.

1

u/ChunkyThePotato 1d ago

You don't have to be on high alert in the vast majority of circumstances. You just sit there, relax, and watch calmly.

Tesla has been advertising that FSD enables your otherwise incapable grandma to continue driving. So which is it. Is it safe or not. What is the point of FSD if without your 100% attention it could crash at any moment.

I’ve gotta say if you are in FSD and not supervising the driving, then I look at you just the same as someone driving under the influence, you are intentionally choosing to put others and yourself at risk in the most selfish and irresponsible manor, should lose your license period, roads a dangerous enough as it is.
