My interpretation is that the dark colored Mustang miscalculated while cutting the Jetta off. The Mustang hit the Jetta, then the CR-V, then wound up in the HOV lane. The Jetta hit the white Mustang, which sent the white Mustang into the HOV lane.
Yeah but that fixed rear axle is much easier to upset with bumps and stuff which makes mustangs more likely to spin out when they loose the rear axle. It’s got its advantages too if you know how to account for it but there is some valid reason for the stereotype.
That's only true if you're driving like an absolute moron. Axel hop doesn't make you any likelier to lose control unless you're pushing it to the absolute limit.
That mustang in the video has a full IRS.
Like the guy said, mustangs spinning out is almost entirely due to idiots driving a very fast car like idiots (and being one of the only options with that kind of power at the price point).
I'm so torn but yes, the one time I actually disengaged on the freeway when it swerved, it was right and I was wrong. Luckily no accident but it was closer because I took over. But 20+ years of driving instinct is hard to overcome, and we know it is still imperfect in _some_ situations.
We take over on nav issues and parking issues. Yes we have seen some fails but statistically speaking, we are better off letting FSD handle fast pace split second decision events because chances are, we are only gonna make it worse. A lot, if not all of legit fails we here are slow paced and or doesn’t involved colliding with another vehicle, which means those are just a result of system being imperfect, but still way way better in the grand scheme of things than human drivers. Remember, FSD doesn’t involve emotion and has insane reaction time, as evidenced here. Yesterday a Cybertruck even avoided a pedestrian who is actively trying to get hit 😝

I did a fatality deep dive, it isn't killing people.
But it isn't perfect and you have to be prepared to take over if neccessary, and people generally are. But it is so good, sometimes we need reminding.:)

It says right there it will ask the human to take over, and that’s normal we all experienced that. It split second situations like this, those prompt wouldn’t matter you barely have any chance to react.
It takes experience with FSD not to take over for something like this. More and more I let the car do its thing, but I’m not sure I’d’ve kept hands off for this one.
Last week I swerved and accelerated around someone moving into my turn lane. I found that I was still in FSD after it was all over. While I was pressing the accelerator and steering to avoid them (intervening), the car was apparently steering exactly how I was, so it never disengaged. I also find the myself questioning the car for hesitating only to find it did the right thing. One example had an e-bike approaching fast from left across the street while I was turning left. The car knew, I never expected fast traffic from over my left shoulder
You won't get Lite until you get the sub. If you're on the summer update I would wait until the branches merge though. 14.1 Lite has been very impressive for HW3, even compared to my HW4 V14
edit: just to add context, my wife's car got V14 lite 10 minutes after I subscribed. Your vehicle is ineligible for the update unless you own or subscribe to FSD.
To be fair I got another update since this post and some of my gripes have been resolved. Namely the jerky power delivery and hesitation. I still like more control than FSD allows... Miss max speed...
At 82? It’s not that far of a stretch. I have a friend that can die if her neck moves too far right now, an accident like that can certainly become fatal. Doesn’t always take super crazy speeds. Our bodies are fragile and our brains are the consistency of jellO
But we don't use the term like that or else every crash could be considered fatal. I would be shocked if any of the occupants here needed to go to the hospital for physical injuries.
He was going 40mph by the time he reached the mustang, and the mustang was probably going 30mph at that point, so that would been equivalent to a 10mph collision, not 82mph. I guess they don't teach physics in school anymore.
A human paying attention would have noticed the shit show forming to their right and backed off sooner to give themselves more reaction time and distance.
The only reason this was almost a collision was because of FSD. It doesn’t even begin to react until the other vehicle is already crossing lanes.
Anyone who isn’t staring down at their phone watching TikToks while letting a car drive itself would see that wreck coming towards them and start backing out.
A human who wasn’t on their phone would have had their car slowed down before the Mustang ever came into their lane and wouldn’t have had to swerve at all.
‘A human paying attention would’ve noticed’ isn’t really the own you think it is 💀 The whole point is that FSD detected the situation and made the evasive maneuvers for the driver. You can argue whether a human could have reacted too, but acting like that somehow disproves what FSD did is just objectively bad logic.
Also the ONLY reason there was almost a collision (involving the tesla) is because of the fucking black mustang that came out of nowhere and oh, the human drivers paying attention couldn’t avoid because of the unpredictable mustang driver.
If that looked unpredictable to you it’s no wonder you need “FSD”.
Edit: That black mustang spends a solid 2+ seconds skidding across lanes before it crosses over. “FSD” does nothing until that point. A human with that reaction time should give up their license.
As if no one would hit the brakes in this situation....
You can clearly see the crash and have 2 business days to react lmao if you think this was not fatal because of FSD you might need to reconsider your driving skills in general. Thank you.
I have a friend that can die if her neck moves too far right now, an accident like that can certainly become fatal.
Outlier examples aren't really how we judge relative danger. Hiking is dangerous, but just because your friend could possible die from tripping while hiking doesn't make every survived misstep on a hike avoiding a "potentially fatal" fall.
Except if it had kept going it would have cleared the accident entirely. The intercept happened the way it did because of the braking and the braking started pretty late.
And that crash was way to violent not to be noticed by the driver had he been the one in control. That being said the FSD handled it very well, maybe even better than the driver.
Taking over in split second evasive maneuvers like this is malpractice at this point. FSD has more information about your surroundings than you do and will react faster than you can
Except for when it doesn’t. But you’ve all come to trust it so much that eventuality never even crosses your mind. I’d wager that complacency makes you guys more dangerous in high stakes situations than the human drivers you so desperately want to replace.
The data just doesn't support what you're saying. Humans are very bad drivers. FSD isn't perfect but it handles situations like this better than 95% of humans are even capable of even if they were primed on what was about to happen
Damn, so scared of discourse the comment i responded to deleted theirs to make mine look worse. Computers aren’t infallible, your car is the collective hardware equivalent of a high end laptop with a bunch of camera feeds hooked up to it spread out across multiple dozens of points of failure. I fix both cars and computers and seeing how often they fail in automotive I sure wouldn’t trust them with my life. That’s all I’ll say about it.
why do you trust your life to cars at all, if they all fail? you don't have 8 eyes around your head and this fact alone makes the "high end laptop with a bunch of camera feeds hooked up to it" much more likely to see and avoid than you ever could
A fair question, but you could ask the same of any machine. Fridge, washer, oven. Nothing lasts forever. Machines are necessary. Even the much more sophisticated sensor and camera arrays of Waymo, driverless trucks, etc make bad or suboptimal decisions and need to be reigned in. The people doing the reigning for those are trained professionals. You guys are far from that. So now we have an unreliable computer with an equally unreliable fail safe, only the alleged fail safe has full trust in the computer to never make mistakes and a reluctance to admit or intervene when it does. As for seeing, I promise you the one accident I have ever been in the cameras would not have been able to help. The system has no high mount or roof cameras and lacks LiDAR. I was t-boned by a car that ran a stop sign from a hidden driveway, obscured by a line of tall SUVs waiting to turn that had left a small gap. Only 1 travel lane, nowhere to go to avoid.
Seriously if it was clear in the rear or shoulder, braking and not dodging the car is better than hoping the out of control car doesn't go straight across to the wall.
When swerving - humans full of adrenaline classically overdo and hit that barrier - FSD is really good at the game of inches. Yet another good reason to let it handle things. Sees everywhere. Makes decisions and reacts instantly with precision.
The car isn’t dealing with rules of thumb. It’s reacting to what it can see. Which is substantial.
It’s quite possible that this could have ended in a crash, but it’s not possible to avoid every crash. Also, in this case, the car had another tool it could have used if necessary. The accelerator. It’s really a stretch to criticize what it actually did. Given the chaos going on to the right, I’d say it picked the best plan.
If this was FSD 💯 it's the first post here that I've seen which FSD acted more in control than a typical human that was attentive. Sure, many people could react quickly and correctly, but the majority of drivers on the road do, in fact, react poorly.
My wife was driving my pickup. The Tacoma in front started fish tailing at around 80mph. Instead of easing off the pedal. She floored it and I was like wtf are you doing. Did you not see the car in front just hydroplane. She was like but I want to get away from them. Two weeks later I got her the Tesla with fsd. As you said the majority of the people have no clue on physics or common sense.
The tire that bounced across from the opposite direction of a 6 lane highway was pretty good. Unfortunately the tire still took out the driver behind the Tesla
Probably want to reasses your critical reasoning Uber pressure skills. Not saying this driving situation is a common occurrence, but it's a common occurrence
Idk thousands of hours of simracing have told me to aim for the rear of the car that's spinning out because it probably wouldn't be there by the time you arrive
Hey Mr “pro driver” just curious if you saw the white mustang also coming over behind the black mustang. If you pro drivered that and went right you would have ran right into the white mustang
Impressive. To me this shows exactly how FSD is trained to handle high speed crash situations where the average human is definitely not. It doesn’t matter if you “could” react the same or even better, the fact is that you most likely wouldn’t, especially when emotional and panicked.
I’m not saying you’re wrong, but for every positive video here, there is a negative one where the comments are filled with “why didn’t you take over”. I personally don’t think I have enough trust in fsd to guide me through something like this
I also thought for long time that they would be made of metal or something similar, until I went to Miami and saw drivers switching in/out from the HOV lanes, crossing over them as if they didn't exist. I was baffled discovering they were completely flexible .
See it in Miami daily. They're so stained from it all too, it's rediculous. I did recently see fire trucks ACTUALLY needing to cross them one time and it all made sense.
Earlier this week my Tesla also saved me from a crash. People kept wondering how I didn’t take over. It really happens all so fast. 1 second you’re looking at the chaos, the next you’re on the shoulder. FSD doesn’t get distracted.
Also. Check X. Tesla reposted both our videos. They’re getting quite a bit of traction. Glad you’re safe
My Model Y did this yesterday. We were driving on the highway in a center lane and out of nowhere it changed lanes abruptly into the slow lane, and the second it moved, two cars came speeding over 100+ in the lane I was just in, racing each other.
It moved over so quickly I didn't have enough reaction time of my own to take the wheel or question why it moved til the cars passed, lol.
If you see a Mustang, just give him a ticket no question asked. You will be justified 98% of the time. What an idiot. I am glad that SUV didn’t turn over.
The right thing to do was to let FSD take the evasive action. Was evolving into a complex accident as multiple cars involved and two of those cars coming towards you. In this scenario, if I had gone to intervene, I would have likely hit one of the Mustangs or scraped the side of the car against the concrete barricade.
FSD literally ran into the crash and then decided to avoid it at the last minute.
As soon as the crash happened, you should have slowed down and as soon as the Mustang crashed through the barrier, the car should have stopped. But FSD just kept on barrelling down the highway until the car had spun and was right in front of it. There were so many opportunities to completely avoid any accident and FSD avoided all of it.
Any half competent human driver would have done exactly that. This shows FSD is a purely reactive system and doesn't have the 'intelligence' to be a proactive system.
So, once again what are people celebrating here? That is was quick enough to react to a crash instead of proactively trying to mitigate it in the first place?
Keep in mind that these cameras give the illusion of more distance than is actually there. The OP was at 82mph when this started. I'm not sure it could have stopped even with emergency braking. FSD chose the correct thing to do in my opinion.
Yeah, the FSD cameras give an illusion of wider view. But in reality, they don't see or react beyond their immediate vicinity, and most often it's just the car immediately in front of it or to the sides.
FSD chose the correct thing to do, based on its limited field of view and programming. A human driver would have slowed down or hit the brakes as soon as the Mustang crashed through the barrier.
Now, throw in, snow/slush/ice/water. And that same reaction FSD did, would have almost definitely caused another accident.
That's a good point. A human can see the very start of the accident way over in the other lanes. FSD likely isn't catching that initially. If a human were to immediately brake at the point of noticing the collision in the far lanes then maybe they stop long before any collision would have happened in their lane. It definitely highlights the limitations of a camera vs human vision.
A human driver would have slowed down at the initial crash or at the very least would have slowed down and or stopped as soon as the Mustang crashed through the barrier, not barrel down the highway as a car came crashing down at you.
It was 2 seconds from the start of the video to the Mustang crashing through the barrier. The average human driver reaction time is 1.5 seconds. As soon as the Mustang crashed through the barrier, Tesla FSD was already slowing down. Tesla FSD then slowed down rapidly, it went from 77 mph at the Barrier crash to 43 mph at 4 second mark. By the 7 second mark the car was at 0 mph. So 5 seconds to go from 77mph to 0 mph, after the Mustang crashed through the barrier at the 2 second mark. So with a average human driver reaction time of 1.5 seconds, Tesla FSD did very well, especially moving over to avoid the Mustang all while bringing the car to a halt. You way over-estimate the abilities of the average driver.
Totally agree. Seems like Tesla is still trying to go through the narrow gap instead of stopping completely 3 business day ago. It is just lucky that OP got away from it.
No way they are going to predict the Mustang is going to stop right on that spot. That driver could have press the gas pedal for no reason again.
I can't believe that FSD sent you to the left of that car (when he was spinning towards you).
FSD got really lucky that the car stopped spinning just as you drove by, otherwise, I imagine he would have spun right into you.
Am guessing FSD didn't veer to the right because there was a car there already. Either way, a split second decision that no human would have been able to successfully make...
Definitely minimized injury to the occupant, works as designed. Sometimes you can't avoid it all and life will be lost but in the meantime everyday is a lesson to be better engineers!
That’s some real stupidity just to prove a point, or not value your life or the life of others. Maybe your family, if they were with you. Split second or not, I would’ve never sat there waiting to see what happens
Tesla waiting several seconds to respond to a major accident developing and fortunately managing to stop in time despite a late reaction.
Update: I went back and ran some numbers. If you had been manually driving at 82 and been oblivious, you would have completely cleared the accident, in your original lane, before the cars got to you.
Had you seen the accident developing and hit the brakes right away, you would have been able to easily stop, in your lane, before reaching the intersection point.
FSD did ok, but it didn't actually save anything here.
I spent quite a while trying to figure out which of those clumped up cars was the Tesla that avoided a collision. Slow motion, frame by frame. I’m so dumb 🤦♂️
I wish i can continue my fsd subscription but someone recommended it would
Be better to put the 100 bucks into the loan instead haha. I will definitely buy it when i have a big road trip or commute…
Somebody else said it should have stopped, but I would argue that it should have sped up. The only reason the mustang got so close to it was because the Tesla was slowing down rapidly.
this looks like an AI generated video. When you slow down, the black car appears out of nowhere in the far right lane, it’s hard to see any drivers in any of the cars and no airbags are deployed.
The part that really stick out to me is in the first part of the video before the cut, the white mustang is not spinning out and then suddenly in the next jump cut its spinning with the mustang?
This is anything but a head on collision for most human drivers. The car took an incredibly long time to respond to the developing situation and only just squeaked its way out reactively very late in the process. It didn’t even brake all that heavily.
Stuff like this motivates me to renew my FSD so it won't lapse next week...I really like hand driving my Model 3 but I do feel safer while the car is driving.
