This happens very frequently. In the Netherlands you are sometimes allowed to drive on the shoulder of the highway near busy cities and you run into exact this situation. Autopilot (I don’t have FSD) freaks out every single time.
That would have tricked me too. It looks like a solid yellow line. Terrible road design.
Agreed.
Despite how good FSD is most of the time, situations like this are concerning. The dashed line on the right was clearly visible, so what did FSD determine was happening here, a merge? But it didn't signal for a merge or a lane change. It makes me wonder what would have happened if there was a car in the lane beside you. Honestly, I think this is a situation where "phantom braking" would have made more sense than just changing lanes without signalling. Edit: it turns out this is Autopilot, but my point still stands.
This is basic autopilot, not FSD. Since the last update, the dashcam recordings show what system is being used: - FSD has a blue text saying "self driving" at the bottom. ([Example here.](https://pbs.twimg.com/media/G7r8nsnWYAEw-Ff.jpg)) - Basic Autopilot turns the steering wheel icon blue (bottom right). Basic autopilot only does lane centering + adaptive cruise control. It will try to center the car between anything that looks like lanes, no matter what. Now the answers to your question: > _"so what did FSD determine was happening here, a merge?"_ Nothing was determined, because basic autopilot blindly follows the lines and that's it. > _"But it didn't signal for a merge or a lane change."_ Basic autopilot don't do that. > _"It makes me wonder what would have happened if there was a car in the lane beside you."_ Under complex situations, Autopilot freaks out and goes into "[take over immediately](https://www.notateslaapp.com/img/containers/article_images/fsd-beta/take-over-immediately-toi-red-steering-wheel.webp/258965334767281e0515149eca0693ed/take-over-immediately-toi-red-steering-wheel.jpg)".
Oops, my bad. I've definitely had phantom braking with lines on the road that were way less sketchy than this though, I'm surprised the car didn't just bake here.
It also has trouble with stoplights where glare is present.
I’d have done the same if I was driving. Look at those line designs, it clearly suggests lane is ending on left so the car moved to the right. It’s a bad road design.
It‘snot bad design, it‘s construction crews not giving a shit. It is not acceptable to have old lines still visible when new ones are drawn or when temporary lines are removed.
I don't think "tricked" is the right word. The lane is very badly marked, the car behaved entirely appropriately
Autopilot stops at lights?
I just got tricked thinking the car did the right thing. 🥲
No because you have 2 human eyes which have way more resolution than a camera. It 100% looks worse on a video than in real life.
I’ve definitely been tricked by things like this before with my human eyes. It’s not uncommon for road crews to do a shitty job
This would happen to any lane keep system using front cameras.
Mine ran a red light once because the sun glare made it look green. I'm guessing it's a rare case but just like the video, you still have to pay attention and take over if necessary.
It is not that wrong tbh
Thankfully the tesla autopilot looks at your blind spots and surroundings before darting over in the lane. My only issue is the full self drive always seems to target pot holes. I constantly have to cancel and manually avoid them. 5 lane choices and it picks the pothole lane each and every time
This is common in Texas, but lines usually run into a divider or other obstacles….
That is not appropriate! The car behaved understandably, given the way its technology works and the way the road looked, but a good driver should recognize: "ok, I don't sharply merge into the lane next to me, this is the lighting being strange."
It is indeed a bad road design, but would you really do the same thing? Even if I did, as soon as I realized the mistake, I would regret being tricked.
I would have done that too, don’t understand tricked.. what was the right thing to do.
Yup, there's a bridge over the highway I go through every day being repaired, under it one lane was cut because of that for a good distance, so all the lanes have a similar yellow line redirecting all the lanes to the ones next to them, and they all look as shitty as the one in ops video
Wouldnt it actually affect all lane keep systems? Unless maybe there's one that blindly works by gps or by the side barriers
Can you retry the test with a car following close behind but in the other lane. Would it still try to merge infront of the other car or continue straight?
Mine dodged a pothole today on the highway I was impressed
It's not a painted line but rather freshly laid asphalt which has a shine/sheen to it compared to the road. It was most likely used to fill a crack or something. Tesla thought it was a lane marker and this is why I don't buy or use FSD, even during the numerous free trial periods Tesla has offered.
Autopilot doesn't stop for red lights, only FSD does.
Its not a real painted line, its one of those tar snakes thar reflect the sun and look like yellow paint
Yep. This is when I decided I didn't care for autopilot. That and the potholes it aims for. Not worth $100/mo. And following others so close when I'm expected to intervene if it fails. It may drive better than most people, idk. I'm not most people, however.
That's what I meant, sorry
Yeah this sort of edge case is exactly why real FSD will be a pipe dream for the foreseeable future.
Consumer grade GPS is not accurate or reliable enough for something like lane keeping. It’s only accurate to within a few metres, which is more than the spacing between lanes.
This is why simply painting over lines isn’t great. The reflectance change causes it to stand out, though jackhammering the paint out and resurfacing would be pricy.
Sun has got nothing to do with it ,happens at night as well...using autopilot during construction zones is dangerous when there are multiple road lines visible. You need to be alert to intervene or just disable autopilot....thats also why fsd can never be FULL SELF driving because it will always need assistance under certain circumstances.
This honestly might've tricked me
"Old"
There was a road like this where I live and I did the same thing when I first saw it..
Alabama?
My dad who was a PM for the DOT for 43 years was over road construction and you've never met a man more passionate over "MOT" (maintenance/movement of traffic). Poor MoT can and has absolutely caused carnage and even death for a bunch of reasons, some the fault of the driver(s), and others due to poor traffic controls (ie poorly removed lines from interstates).
Free lane change without EAP or FSD!
Did they not just push an update to fix this?
Yeah thats what I wanted to mean with blindly, yup basically being as reliable as going blind
Nope. Doesn't happen on my comma
FSD beta is not available for consumers in Europe, OP is from Italy and this is just the normal auto steer.
If its an old line just remove that crap, seriously. This is for humans confusing let alone machine learning systems
lol you people are such a cult
Yes that happens
Not if it only used side cameras, like a lane assist feature, since the glare is a factor of sun angle.
Comma isn’t a lane keep technology specifically. This would t happen with FSD, and probably wouldn’t happen with Waymos either.
Once fleet reporting is in, pothole avoidance can be godlike. Every car choosing the smoothest line down every street based on the experience of every Tesla that has gone before. Until then, around town FSD is unusable where I live.
Well, how would a side cameras only lane assist behave if there was a zone without visible lines be it because of bad maintenance or any other reason? I can use autosteer in my urbanización without problem going at like 30kph even going over bumps and do any sharp turn, and there are no lines drawn, is the no visible lines a drawback for side cameras only?
How would you describe the comma then?
Damn got me too looking at the footage
My consumer grade racebox device has a precision of about 0.2 meters usually.
Or in rain.
I think car is making a choice between honoring solid line vs dotted line which it obviously chose the correct. It’d rather cross dotted line than solid. I would have immediately gone back to left lane after figuring out the inaccurate lines but I guess car decided to stay in right lane.
This needs more upvotes.
So a legacy piece of software from 2016. Yeah this is a non-story.
What would you expect it to do?
This happens to me a lot on Colorado. Low sun angle or wet roads and these grooves look just like the other elane lines (sometimes ever more like them since our main line lines fade often). Once you learn them you can ignore them, and FSD won't "learn them" for future trips, so it wont ignore them, but the road really should be cleaned up better .
Autopilot can definitely afford to do better. I had similar situations where it makes similar mistakes, it takes turn lane markings from perpendicular road as its lane and ends up swerving to the wrong lane. In this particular case, it should technically recognize that the marking was invalid due to the surrounding lane markings.
I'd do the same if I were a camera.
I’d probably have changed lanes myself because you never know what’s coming after when there is a solid line like that.
Most systems today only work with clearly visible lines.
Last I was tracking it was attempting SAE level 3 driving assistance.
I am having such issues every day. Place where I am has many roads with worn out drawings so not tesla but even my eyes quite often can not solve the puzzle In this shot... well...not that obvious at the very first point what you actually see
Stereoscopic vision allows humans to determine what is a reflection (of sunlight in this case) vs. a solid albedo colour of a surface. Most humans, given this situation in real life, and determine a painted line vs. the black asphalt paint stuff. The car failed the perception test, like most monocular cars would.
Poorly marked lane. I think the real test would have been how the car would react if there was another car to its right in the lane it went into.
Comma is level 2, not level 3.
Lmao despite the downvotes, my Comma also doesn't react this badly in the same scenario. Jacksonville is always under construction so this is pretty common
Cant wait until these systems are more common and a family dies in a crash for some redditor to say "the car behaved entirely appropriately"
I love FSD and use it all the time… But no way is it worth $10,000. I am so glad I paid $2000 for it in some kind of flash sale years ago. It’s getting better. It will get there. But no way is it worth what it is today nor what Elon Musk is saying it is today.
This is not the fault of the FSD system but rather the fault of the construction company failing to cover those lines up properly.
Lmao bro almost 300 downvotes
I would be fooled myself.
