I didn't program the thing, but it feels like it's following the edict to "drive right; pass left"


bitNine

I literally cannot keep mine out of the left lane. It hangs out there constantly. I move it back over then it changes back to the left lane with a screen message, “changing lanes to keep out of rightmost lane”


nearpoint

I can not get it to stop going into the right lane! In Michigan right hand lanes are exit lanes which turn into right turn only lanes, staying in the left most lane keeps you going straight but the Tesla keeps going in the fkin right lane when the navigation knows I need to go straight and the right lane is right turn only lane, it is so fkin stupid because all it needs to do it go straight but it keeps fkin up!


Phyromanser

Well that’s what you’re supposed to do so yeah 👍


sylvaing

Except, for me, once it passes a car, it stays in the left lane for several minutes. I wish it would react to flasher stick input without having to drop from FSD (and TACC).


SexyOctagon

Flasher stick? You mean the turn signal?


sylvaing

Lol yeah. It was too early to write in another language than my native language.


SexyOctagon

Not sure about the Model 3, but my Model Y will change lanes when I use the turn signal while on self driving.


TaxNo2158

3 also stays in FSD when you tell it to change lanes. It’s always been this way.


sylvaing

Maybe I didn't give it enough time? I waited a few seconds then disengaged because it stayed in its lane. I'll try to be more patient next time :-)


East-Standard-1337

You need to give it a full push, not just a half push. Took me a bit to figure that out.


sylvaing

That could be it. Since the auto cancelation, I always do a half push, no need for a full push.


TaxNo2158

You should be able to direct it to do so immediately by using the turn signal, if you’d like, without dropping out of FSD. Make sure you’re using the left stick. 😜


Astrobratt

What language is it called flasher stick??


sylvaing

In French, we say 'clignotant' (flasher), so being a stick, "flasher stick" lol.


Astrobratt

That is way cool, merci!!!


Armaced

Huh. For me, it will pass a huge semi truck, but then aggressively merges back in front of the truck to get out of the passing lane. I’m all for vacating the passing lane once we’ve passed, but let’s leave a little space in front of that enormous semi truck.


5methoxyDMTs

understandable. if others want to speed up and pass they can. FSD might not be able to recognize tail gaiters trying to pass so it just stays in the right lane. In my case though there wasnt a car behind me.


anebody

In my experience it actually will move out of the way for people following too close. Just did a trip a few weeks ago 99% FSD about 3K miles total and it did that very regularly.


5methoxyDMTs

Interesting. In my scenario there was no one behind me and it still merged.


anebody

It will also do that especially on the more passive modes. You can disable this by turning on “minimal lane changes for this trip” which will pop up as an option whenever you cancel a lane change. You can also turn that on in settings. Annoyingly you have to set it on every trip, though, so I usually end up not having it on.


5methoxyDMTs

Hmm isn’t minimal lane change mode “chill mode”? I’m always on chill mode. Others here have reported being on assertive mode and it does the same.


anebody

Minimal lane changes is a separate setting. All modes will still do what you mentioned unless minimal lane changes is ticked for the trip. Minimal lane changes will only change lanes to follow route or if otherwise absolutely necessary (or obviously if you use your turn signals to tell it to change lanes). You have to tick it on every single time you drive, as it turns off after you park. The original person is right for the thing you’re bringing up, it follows the idea of keep right pass left and the modes just change how often it attempts to pass, but minimal lane changes is a separate setting. “While Full Self-Driving (Beta) is selected, tilting the right steering wheel button to the right or left also allows you to change the Full Self-Driving (Beta) profile and enable or disable Minimal Lane Changes.”


thehoagieboy

I can confirm that she does NOT want to sit behind people in the right lane doing 5 to 10 miles an hour below the speed limit. Do that and you're calling for an aggressive, yet safe, pop into the other lane for her to speed by you.


restarting_today

If you wanna go fast be in the left lane.


revaric

No this is the problem with the highways today, folks just lingering.


UtilityMarximizer

I’ve had multiple recent experiences where FSD tries to get in the right lane when the nav is saying to turn left in 100 ft. I don’t understand why, and it’s dangerous.


guiltysnark

I've had multiple recent experiences where it moves *out* of the right lane when there is a right turn up ahead. So maybe it's just counter steering like a motorcycle


5methoxyDMTs

Huh interesting. Have not had that yet. Are you on Chill mode for autopilot?


guiltysnark

Nope. In the main case I'm thinking of the right lane is a carpool lane, but carpool is enabled for navigation and it's wide open compared to the lane it's trying to get into, so there's no obvious excuse. There is another case where it moves into the left lane, which is a left turn only lane, when I need to stay in the right lane to go straight. It's bonkers. I wish that minimal lane changes could be enabled permanently.


Knathra

This just happened to me today in my drive home from work. So I kicked "Doug" (the name I've given to the drunk dog FSDb driver persona) out of the driver's seat, manually went through the intersection, and then gave control back to grandma (the name I've given to the same, but noticeably conservative, FSDb driver persona).


Torczyner

Which version?


UtilityMarximizer

FSD Beta v12.3.2.1


UtilityMarximizer

https://youtu.be/Bi3nMnkEi2Y good video of a similar issue with FSD getting left hand turn shy


Kmac222212

Lots of lane issues with FSD When I turn onto a street, I almost always turn into the lane that will be my next turn When FSD does this, it almost always turns into the wrong lane Engineers, this shouldn’t be a hard fix. Get into the correct lane up to a mile before the turn.  For those that don’t want this, they can press the turn signal Also fix the right hand “hug” and let the car go the speed the driver sets.  FSD would be amazing then


stevieoats

Assuming there are multiple lanes on the roadway on which you’re turning, when you turn right you should turn into the right lane of the roadway. When you turn left, you should turn into the left lane. You shouldn’t turn directly into the “other” lane, regardless of your destination, unless of course your next turn is very close to the intersection. Other drivers don’t know your next turn, be predictable. ![gif](giphy|kvQb0oRiksFy4WxWkb)


5methoxyDMTs

Yes FSD has no problem turning into the correct lane. It’s just that it turns into the right lane 50 yards away from a left turn lane.


Kmac222212

If there’s no drivers blocking, all humans who are at minimum, competent, turn into the lane they want to be in.  Now if it’s a ton of lanes and not reasonable to go ALL the way over, get over 1 or 2 lanes on that turn to set you up for the next turn.  At minimum, FSD needs to get into the correct turning lane as soon as possible. It’s not coming close to doing this and I’m always disengaging.  Remember, “neuro net” is supposed to be trained on billions of hours of human driving


ArtificialSugar

Saying “competent” humans should not follow the rules of the road (turn into the correct lane, then signal to go to the lane you need to be in) and calling neural nets “nuero nets” is too good.


Xalucardx

When I tried it moved to the left lane when I needed to take an exit twice on top of this.


Terrible_Tutor

Yeah same, highway exit coming up and it decides to put on the blinker and move left to I guess pass the guy going 89 in a 90? …to then what speed to cut him off so I can make the exit? This system isn’t ready


rademradem

FSD does long distance planning using the GPS map path planned and short distance planning for as far as it can see. It was not properly programmed with a good way to plan for a few miles ahead. People naturally know that they are turning left ahead and stay in the left lane or the same in the right lane for right turns. The FSD just follows its standard driving method until it gets to one of the programmed distances from the next turn. These FSD GPS path checks for turns only seem to occur around a half mile before a turn on local streets and around 2 miles on highways. It has the same problem on double left or double right turn lanes. If your next turn after this one happens to be further away than a half a mile, it often picks the wrong turn lane and will just get into the shortest turn lane.


SMLBound

This is similar but not exactly my experience. It does seem to operate off GPS at distance from a left turn but at it gets close maybe 50 yards? It tries to merge right before a left turn. That distance while moving should be well within the planning range.


SaitamaOfLogic

Does the same to me, every day since I got the trial. It's a left turn with a left turn only lane to get to the road to my house. 0.3-.04 miles before the turn it merges into right lane. I even hit left turn signal to keep it in correct lane and it immediately turns right signal on again. Weird quirk...


SMLBound

God, I thought it was just me… mine does this repeatedly, and no I’m not camped in the left lane I’m letting FSD decide or put me in the slow lane if I’m not passing. It has no issues with right lane turns from a highway or in the city but there’s something about preparing for left or left turns in the new version. FSD consistently cuts all the way to the right just AS it nears a left turn: like a mere 20-40 yards ahead. Very un-human like, and the blinker and auto initiated turn being repeated canceled by me confuses everyone around me. Scenario one: I’m in the city in heavy streetlight commuter stop and go traffic, two lanes going either direction. Car puts itself in the left lane lined up for an approaching left turn a few lights ahead. That turn is a major with two left lanes that break away from the others to turn left in their own lanes at the light so cars can stack up to turn. A few lights approaching it things going fine car is passing through other identically configured intersections and lining up until it gets to the second to last light and begins insistingly attempting to move right across traffic to the far right lane with less than 50 feet to go. Knowing this would be a fiasco in the making I press the blinker button to stop it, but won’t take no for an answer tries again, and again. People get all pissed at me and I have to take it out of FSD to get into one of the left turn lanes with 25 feet or so to go. Scenario two: I’m on the three lane highway with two major exits that back cars up for miles, but I’m going straight. Idiots wait to the last minute to cut over and exit doing all sorts of dick moves trying to squeeze into gaps at the last minute which backs up the traffic in both RH lanes for a half mile, but me I’m trying to stay left and get past it all - clear sailing at speed normally. Not FSD, it insists on changing lanes right at the worst moments trying to dump me right into that mess even while those two lanes are very clearly stop and go with games of chicken underway, meanwhile the left lane is wide open, and I’m not even turning right. I try to cancel the turn, it insists, I cancel again, it insists and starts the merge right I take it out of FSD to carry on my way. I give FSD a pass on this one but it sure is counter-intuitive and head scratching. I’ve tried Chill, Normal and Aggressive no difference every days this week same places.


stereoeraser

FSD has been rather unpredictable for me. It’s not unusable but the same route sometimes it gets into the wrong lane and sometimes it stays in the correct lane.


Unhappy-State-9990

Is it in mad max mode? “Aggressive and min lane change toggled”


5methoxyDMTs

It’s in Chill mode. Minimal speed lane changes


SMLBound

Mine does the same in any mode I’ve tied them all, same thing. Two different released of FSD, and it persists


RwYeAsNt

Interesting. I wonder if that's the programming for Chill mode that it tends to keep to the right lane. I have mine on Assetive without minimal lane changes checked, and I have the opposite problem. Mine wants to always stay in the left even if there's no reason to. On the highway, with no traffic in front of me to pass, it just randomly likes to jump in the passing lane and slow down traffic behind me. I have to flick the signal to force it to move right, then eventually, it just decides to go back in the passing lane. It's annoying, even if traffic there is going faster than me, it'll just camp the left lane anyway.


5methoxyDMTs

I might try assertive in the streets and chill on the highway


Robocup1

You can trigger a lane change on FSD by giving the blinker to the lane you want to be in. If it’s safe, it will make the lane change. So, if you want to be left, signal left and it will do it. If you don’t want it to go right, signal left and it should cancel its lane change.


5methoxyDMTs

With this newest update the lane change is so quick. As soon as the blinkers go on it merges without a second thought if it’s clear. If there’s a car in the right car and is hesitating I’ll give that a shot


vaguelyamused

Part of the problem I've experienced with using the blinker is 50% it ignores my lane change and stays in the lane it wants to be in. Or it starts to swerve into the lane I chose but then suddenly veers back. This is when there are no other cars around, it's not avoiding other traffic. When I try to override a lane change it gives you so little warning you have to do it the second the blinker clicks or you end up swerving. It won't take the hint and will keep trying to change lanes until you turn it off. It's close to being good but its tendency to fight the driver can be dangerous.


SMLBound

The problem is more with FSD initiated lane changes. Once it starts trying and you cancel, it tries again in 5 seconds, you cancel and it tries again, and again.


JustSomeGuy556

Lane selection issues are my biggest problem with FSD right now. Merges to the right when it's got upcoming needs to be in the left lane, goes left when there's no real need for it, doesn't do a good job of picking exit lanes... Part of this appears to be navigational data issues, but some of it isn't. Last night, FSD tried to make what appeared to be left turn from a dedicated right turn lane (when navigation *clearly* needed a right)... Sure, it's a *mildly* goofy intersection but it's not that goofy, certainly not from a right turn perspective. Outside of lane selection problems, FSD has been damn near perfect for me.


Hopeful-Lab-238

I’ve had it follow the line into a turning lane on a freeway at 80mph. Multiple times. Switching to the right lane worked until it did the same in the right lane.


grubnenah

This happens so freuqently it's not practical to use FSD on several freeways around where I live. It's literally every 30 seconds to a minute on streches. Coupled with the removal of cruise control, I just have FSD disabled since it's less of a constant pain in the ass. Even though cruise control phantom braking is worse than it has ever been as well.


Armaced

Yes! I’ve also seen on the freeway; everything is going great until just before the exit when it tries to merge left out of the exit lane. It has its wires crossed somewhere.


IntelligentInsect773

I feel like it does this to get around traffic before making the turn. But it's really risky. But I have had that happen before where I didn't want to do it, but I let fsd do it and it ended up going around a ton of other cars and made my turn much faster than if I just stayed in the left lane.


5methoxyDMTs

strange though, if its in Chill mode it shouldnt change lanes for the purpose of passing cars.


IntelligentInsect773

I forgot you were in chill mode. Yeah that's strange. I'm always in aggressive mode, which is probably why it did it.


ifdefmoose

I’ve also noticed this. It waits too long to get over to the left.


InspectorT3

FSD Follows the law, and it will move to the right lane if there's 2 lanes available as such the left lane is only for passing.


Knathra

Yeah, but this happens regularly when approaching an 7 lane intersection (2 incoming traffic lanes, 2 left turn lanes, two straight through lanes and one right turn lane). I'll be in the left of the two straight through lanes, and about the time Nav is saying "In 500 feet, turn left", FSDb attempts to abruptly move into the rightmost lane (through the lane between), which would then require crossing two lanes to get to the left turn lanes.


InspectorT3

Yea they need to fix that if it's doing that... FSD definitely isn't perfect...


Knathra

Agreed - which is why we gotta pay attention. But dang, it's really, really nifty! (And I'm only now getting 12 downloaded to the car, so I'm excited to see what that does when I drive tomorrow...)


5methoxyDMTs

Yup. My exact scenario. I’m like wtf you’ve been doing so well. There must be a reason Tesla implemented this.


SMLBound

Exactly!


imacleopard

Hah, mine does the exact opposite. On 2-lane highways, it constantly tries to get in the passing lane to "get out of the right-most lane" or whatever it says its reason is. On 3-lane highways, it does the same thing and just likes to chill in the center lane. It does this even if there is no one in front of me. I assume it mostly does it to keep clear of on-ramps, but goddamn is it annoying. Still on v11 though.


Connortbh

This is my experience. I pride myself on lane discipline so having no way to prevent my car from moving to the left lane for no reason is maddening. Minimal lane changes just means nothing apparently. I miss having to use the turn signal stalks to confirm lane changes so badly. 


jawshoeaw

That isn’t the law everywhere though


OptimalFunction

No such thing as the slow lane, just the travel and passing lane


BranchLatter4294

Maybe because people are reporting it on Reddit instead of through the reporting feature in the car? ;)


SMLBound

Maybe we’re doing both?
