While on FSD and clearly marked roads, does your CT hug the left line and occasionally go over it?

[The Duke]

I recently had service for cosmetic flaws on our CT. I mentioned the left line hugging, they did a test drive and verified that it did not center and occasionally drove over the left line. Service did a wheel alignment and told me to keep sending in bug reports as they had no other answers.

The poll is to see how widespread the problem is. Our Model S, son's X and 3 all stay centered in the lane. A test drive in a Y showed it centered as well.

Mine is pretty good about staying centered, except sometimes on inside curves to the right. There, it sometimes drifts on to the centerline while in the curve. I suspect it has to do with the 4 wheel steering not being completely accounted for, but who knows.

I let it drive daily over a very narrow bridge, and it does fine.

12.5.5.2 felt worse than 12.5.5.3 to me, centering-wise.

Our cybertruck recently (last 3 weeks) did a 3000 mile roadtrip, mostly on FSD.

The issues we experienced were:
* On FSD it occasionally hugs and goes over the left lane line. It is fully aware that it is doing so, showing it as doing so on the visualization, but it does it anyway, and for no obvious reason. This happened about 5 times badly enough that a human had to intervene.
* Using "natural speed" it would go as high as 81 in a zone where it also believed the speed limit is 55. It just doesn't care about the speed limit in that mode.
* Lane keeping still poor on roads and freeways with curves.
* Not being able to use the bed outlets while L2 charging is a real hassle on a roadtrip (taking a powered cooler to keep fridge stuff).

Overall the Cybertruck was great for the roadtrip.
* Ran the powered cooler in the bed to keep plenty of fridge food and leftovers, didn't have to go to restaurants all the time.
* Lots of bed space for our gear and a bunch of tools.
* Bought an EGO tool while on the trip, but on a tight timeline that day... so we charged it in the bed while we drove.
* managed to get to 350kW at a non-Tesla charger (St George UT at the walmart)
* at the national parks it gets more attention that elsewhere, due to lots of Europeans visiting who haven't seen one.

What adapter did you use in St George?

Stays mostly centered while driving straight, but a right turn it's hugging the left pretty closely. Turns to the left for some reason are much better...can't remember the last time it hugged on the right.

Have driven ~300 miles on FSD now on a variety of trips/circumstances from local roads to highways. Have not noticed a 'hug left' issue, but I have noticed the following:

• 90 degree right-hand turns, will make a mid-turn correction because it poorly estimates it's turning
• 90 degree left hand turns with a center median, will typically cut the inside too tight and can hit/run over the center median if you let it
• On highways, tends to chase bumpers and follow too closely, follow distance is not adjustable yet
• Braking is quite poor in all scenarios except open roads. In local traffic even heading into stopped traffic at a red light it will hold constant speed until very late and then stomp hard on the brakes instead of letting off earlier, like a human would do, and gently slowing down while regenning to a stop
• In local roads, will cut vehicles off when turning into a lane of moving traffic. Cybertruck doesn't care.

It's occasional but more frequent than I would expect. But it's one of the problems that keep me from using FSD more often. That one mistake can wreak havoc and panic for me and other motorists.

https://www.amazon.com/gp/product/B0CXDWZ193/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&th=1

is the one we have. It only advertises up to 250kW so I don't know if it is a good or a bad thing that we achieved 350kW when the adapter only lists 250kW. I preconditioned the battery by navigating to a nearby supercharger.
Note also the distance since last charge was 275 miles from 96% to I think 11%.
We couldn't get higher than 96% as it was -9C outside where we were charging.

This pretty known.

I do notice that it hugs the left line a bit, however, I've never had to disengage because of it. If your CT is hugging the line and you feel the need to disengage because of it, then just leave a voice report. In time this will get resolved.

Is anyone aware of recalibrating cameras making a difference?

I also noticed that on the holiday update (Model Y), the maintenance schedule says to clean the inside of the windshield where cameras are as needed. I'm sure I should do this soon on the Cybertruck due to all the off-gassing.

I recently had service for cosmetic flaws on our CT. I mentioned the left line hugging, they did a test drive and verified that it did not center and occasionally drove over the left line. Service did a wheel alignment and told me to keep sending in bug reports as they had no other answers.

The poll is to see how widespread the problem is. Our Model S, son's X and 3 all stay centered in the lane. A test drive in a Y showed it centered as well.

I frequently have to intervene on left turns or it will cross over the line. They need a broad sweeping arc rather than an initial 45 and another 45 degree turn to make the 90 degree left.

I am also having a problem with the left lane hugging the left line and at times driving over it. I even noticed when making a left turn around a median it corrected itself by swerving to the right.
It's definitely not safe because it puts you in danger of driving over debris and on some roads drainage grates. Its definitely causing tire damage.

 

[oisiaa]

It depends. I've definitely seen it hug the left line, but on subsequent drives it does fine. Some weird software glitch. In this situation, if I manually drive, the lane departure warning will go off if I move to the right even if I'm still in the lane so it's as if it is detecting the right lane limit as being farther left than it really is.

Service center in Fremont (near factory) did NOT know about this. I am pushing the issue upstairs there.

As per usual there aren't enough choices in this poll. The CT hugs the left in some cases, hugs the right in some cases, and centers in some cases. I am not sure what logic is driving the cases because it is an ML model. In the 'old days' we knew that it was moving away from semis, but now we are told by influencers that it moves away from 'dangerous driving'. The extra option I'd have added would be 'hugs left, right, and center under different scenarios'.
